Boron-Nitrogen Compounds Although the chemistry of boron is still relatively young, it is developing at a pace where even specific areas of research are difficult to compile into a monograph. Besides the boron hydrides, boron-nitrogen compounds are among the most fascinating derivatives of boron. Nitrogen compounds exist in a wide variety of molecular structures and display many interesting properties. The combination of nitrogen and boron, however, has some unusual features that are hard to match in any other combination of elements. This situation was first recognized by ALFRED STOCK and it seems proper to pay tribute to his outstanding work in the area of boron chemistry. One should realize that about forty years ago, STOCK and his coworkers had to develop completely new experimental techniq'\les and that no guidance for the interpreta• tion of their rather unusual data had been advanced by theoretical chemists. In this monograph an attempt has been made to explore the general characteristics of structure and the principles involved in the preparation and reactions of boron-nitroge~ compounds. It was a somewhat difficult task to select that information which appears to be of the most Springer interest to "inorganic and general chemistry" since the electronic relationship between a boron- nitrogen and a carbon-carbon grouping is reflected in the "organic" character of many of the Softcover reprint of the 1st reactions and compounds. original 1st ed. 1965, VIII,

  • 04. Si Monsters
    IV The Chemistry of Bug-Eyed Silicon Monsters 1. The Rise and Fall of an Analogy Carbon and silicon were not always regarded as isova- lent analogs of one another. The great Swedish chem- ist, Jöns Jakob Berzelius (figure 1), who was the first to isolate silicon as a simple substance in 1823, thought that it most resembled boron (1, 2). This assignment was based on the fact that both elements formed acidic, nonvolatile oxides which could act as glass formers, and on a similarity in the appearance of the simple substances themselves, both of which had been pre- pared only as highly-impure, amorphous, nonmetallic powders. This analogy was further reinforced by errors in the determination of their atomic weights, which assigned the analogous formulas, BO3 and SiO3, to their respective oxides, in sharp contrast to the formu- las, CO and CO2, assigned to the oxides of carbon. With the gradual correction of atomic weights and the equally gradual substitution of “stoichiometric type” or valence, in place of acidity and electronegativity, as the preferred basis for chemical classification, silicon was reassigned as an analog of carbon. In 1857, the German chemist, Friedrich Wöhler (figure 2), discovered silicon tetrahydride (SiH4), the stoichiometric and structural analog of methane (CH4), and the logical starting point for speculations on an Figure 2. Friedrich Wöhler (1800-1882). alternative organic chemistry based on silicon rather than carbon (3). Ironically, however, Wöhler did not consider this possibility until 1863 and then only as a result of a faulty interpretation of his experimental data. Having obtained, via the hydrolysis of magne- sium silicide, a series of apparent compounds of sili- con, hydrogen and oxygen, he found it very difficult to assign them exact formulas.

In 1922 he married Ava Helen Miller (died 1981), who bore him four children: Linus Carl, Peter Jeffress, Linda Helen (Kamb), and Edward Crellin. Pauling is widely considered the greatest chemist of this century. Most scientists create a niche for themselves, an area where they feel secure, but Pauling had an enormously wide range of scientific interests: quantum mechanics, crys- tallography, mineralogy, structural chemistry, anesthesia, immunology, medicine, evolution. In all these fields and especially in the border regions between them, he saw where the problems lay, and, backed by his speedy assimilation of the essential facts and by his prodigious memory, he made distinctive and decisive contributions. He is best known, perhaps, for his insights into chemical bonding, for the discovery of the principal elements of protein secondary structure, the alpha-helix and the beta-sheet, and for the first identification of a molecular disease (sickle-cell ane- mia), but there are a multitude of other important contri- This biographical memoir was prepared for publication by both The Royal Society of London and the National Academy of Sciences of the United States of America.

  • John D. Roberts
    John D. (Jack) Roberts 1918 – 2016 John D. Roberts, the Institute Professor of Chemistry, Emeritus, and one of the most influential chemists of the 20th century, passed away on October 29, 2016 at the age of 98 following a stroke. John Dombrowski “Jack” Roberts was born on June 8, 1918 in Los Angeles, California. He spent most of his 98 years in Southern California and witnessed first hand its transformation from a reasonably under- populated region into one of the world’s busiest metropolitan areas. In fact, Jack (or “JDR” as he was oft referred in the labs at Caltech) was born essentially right underneath what is now the famous four level interchange connecting the 101 and 110 freeways in modern day downtown LA. JDR also witnessed the growth and explosion of science and in particular chemistry over that century span. As summarized in his J. Org. Chem. 2009, 74, 4897-4917 article and numerous talks over the later part of his life, the explosion of instrumentation capabilities available to the organic chemist progressed in the course of his scientific career from no less than the melting point apparatus to some of the most advanced instruments on the planet. Without doubt, the advances most influential to JDR’s monumental career in chemistry were the advent of nuclear magnetic resonance (NMR) spectroscopy and the accompanying explosion in computing. Combined, these tools greatly facilitated the insightfully designed experimentation and careful analyses that became the hallmark of JDR’s career. It is clear that Jack’s thoroughgoing nature combined with his deep understanding of instrumentation and fundamental chemistry served as an inspiration to nearly four generations of scientists.

    Walter Loveland Oral History Interview, July 22, 2015 Title “Of Glenn Seaborg and Super Heavy Elements: A Nuclear Chemist Looks Back” Date July 22, 2015 Location Valley Library, Oregon State University. Summary In the interview, Loveland discusses his colorful family background and upbringing in blue-collar suburban Chicago. He also describes his earliest interests in science, his path through undergraduate and graduate studies, and those who influenced him as he made his way through his higher education, including his contacts with luminaries like Charles Coryell and John Huizenga. From there, Loveland begins to reflect on his long association with both Oregon State University and the University of California, Berkeley. In so doing, he shares his memories of his initial impressions of OSU and Corvallis, his first contacts with Glenn Seaborg, a few initial research experiences in research, and his impressions of Seaborg as a personality. He likewise recounts his interactions with Linus Pauling as well as major figures in nuclear science at OSU, Chih Wang, John Ringle and Dale Trout among them. Loveland next recounts his memories of the Radiation Biology program at OSU; discusses the life and career of a former student, Sister Mary Joseph Bouchard; and comments on the climate for women and people of color in the sciences at OSU and in the community at large. Loveland's research is the next focus of the interview. In this he provides an overview of his work with super-heavy ions while also describing his research collaborations and the frequent trips to Berkeley that these collaborations demanded. He also recounts his interactions with OSU's Campus Radiation Safety Committee, his disinterest in working at the Hanford Nuclear Site, his experience of co-authoring two books with Glenn Seaborg, and hindrances to scientific advancement that he has noted as a result of denials of security clearance.

  • Dr. Linus Pauling Named Recipient of Priestley Memorial Award
    Dr. Linus Pauling named recipient of Priestley Memorial Award December 16, 1968 Dr. Linus Pauling, Professor of Chemistry in Residence at the University of California, San Diego, was recently named the 18th recipient of Dickinson College's Priestley Memorial Award. Presentation of the award next March 27 will be the highlight of the annual Priestley Day celebration at the Carlisle, Pa., college. Howard L. Rubendall, Dickinson president, said Pauling will be honored for his work in physical chemistry. The award is named for Joseph Priestley, discoverer of oxygen, and consists of a portrait medallion of Priestley. A check for $1,000 accompanies it. Dickinson, which owns one of the largest collections of Priestley memorabilia in America, created the award in 1952 to recognize modern scientists for research, discovery or other production benefiting mankind. Pauling is a winner of the Nobel Prize in chemistry and also holds the Nobel Peace Prize. During recent years, much of his work has been on the application of chemistry to biological and medical problems. Last spring he advanced a highly controversial theory that mental patients could well be treated by giving them "optimum amounts" of vitamins, amino acids and certain fatty acids. During the early war years, he worked on rocket propellants and other explosives but was among the scientists who opposed dropping atomic bombs on Hiroshima and Nagasaki. His work to abolish war began in 1945. Few scientists have been honored so often. Pauling holds the Roebling Medal of the Mineralogical Society, the American Chemical Society Award in Pure Chemistry, the Nichols Medal, Presidential Medal for Merit, Gibbs Medal, Richards Medal, the Gilbert Newton Lewis Medal, the Davey Medal of the Royal Society, the Thomas Addis Medal of the National Nephrosis Foundation, the Phillips Medal of the American College of Physicians and other awards.
