Boron-Nitrogen Compounds
springer.com Chemistry : Inorganic Chemistry Niedenzu, Kurt, Dawson, J.W. 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. -

Philip D. Lane Ziegler-Natta Catalysis: the Nature of the Active Site Literature Seminar April 3, 1992 Karl Ziegler, While Study
47 Ziegler-Natta Catalysis: The Nature of the Active Site Philip D. Lane Literature Seminar April 3, 1992 Karl Ziegler, while studying ethylene insertion into aluminum-alkyl bonds, serendipi tously discovered the effect transition metals had on ethylene polymerization. He and Guilio Natta made significant contributions to the catalytic polymerization of olefins using a transition metal from groups 4-8 and an organometallic from groups 1, 2, or 13, the most famous com bination being TiC4 + Al(C2H5)3 for the polymerization of polyethylene. The Nobel Prize in Chemistry was awarded to them in 1963 for their contributions in this area [l,2]. The impor tance of this catalytic process can be seen by the amount of polyethylene produced in the U.S. In 1990, 8.3 billion lbs. of high-density polyethylene were produced [3]. The heterogeneous nature of Ziegler-Natta catalysts make them difficult to study [l,4,5]. Despite improved techniques for studying surfaces, information on an atomic level about the active sites remains elusive. For example, the surface reaction of [Zr(allyl)4] with SiQi leads to different surface species [5]. It is not clear which of the resulting surface species is responsible for the polymerization process. Various mechanisms [6,7] have been proposed for Ziegler-Natta catalysis, with the most widely accepted proposal from Cossee and Adman (Figure 1). The aluminum-alkyl is suggested to be responsible for alkylating the transition metal which is in an octahedral environment with one site vacant. Ethylene is thought to coordinate, followed by direct insertion into the metal-alkyl bond of the transition metal. -

The First Hydrides of Boron
UNIVERSIDADE DE LISBOA FACULDADE DE CIÊNCIAS SECÇÃO AUTÓNOMA DE HISTÓRIA E FILOSOFIA DAS CIÊNCIAS UNDER THE CARBON SPELL: DIBORANE’S PUZZLING STRUCTURE AND THE EMERGENGE OF BORON CHEMISTRY Nuno Manuel Castanheira de Figueiredo Dissertação orientada pela Professora Doutora Ana Simões, da Secção Autónoma de Filosofia e História das Ciências da Faculdade de Ciências da Universidade de Lisboa. MESTRADO EM HISTÓRIA E FILOSOFIA DAS CIÊNCIAS 2011 Resumo Este trabalho apresenta o primeiro estudo sistemático da história da química dos boranos, compostos de boro e hidrogénio cujas estruturas e natureza das ligações químicas desafiaram de forma irredutível a teoria da ligação química até aos anos cinquenta do século XX. Actualmente, a química do boro é um dos mais promissores ramos da química, com um vasto leque de aplicações às indústrias química e farmacéutica, à nano-tecnologia e à medicina. Neste último ramo, destacam-se as aplicações na luta contra o cancro e no desenvolvimento de medicamentos com um elevado grau de especificidade e inovação. Num futuro próximo, espera-se que a química do boro seja capaz de operar uma verdadeira revolução social, posicionando-se como uma poderosa alternativa à química do carbono que será capaz de oferecer todo um novo mundo de aplicações inéditas. Estas são o resultado da fascinante capacidade do átomo de boro para se ligar de formas surpreendentes e formar complexas estruturas que se baseiam em compostos de boro e hidrogénio (boranos). A grande apetência do boro para se ligar ao oxigénio impede que os boranos existam na natureza. A grande susceptibilidade destes à acção da humidade e do ar torna-os especialmente instáveis e difíceis de manusear e preservar. -
Karl Ziegler
K ARL Z I E G L E R Consequences and development of an invention* Nobel Lecture, December 12, 1963 The awarding of the Nobel Prize for Chemistry for the year 1963 is related to the precipitous expansion of macromolecular chemistry and its industrial ap- plications, which began precisely ten years ago at my Max-Planck-Institute for Coal Research, in Mülheim/Ruhr. The suddenness with which this began, and the rapidity with which it was propagated are comparable to an explosion. The energy carriers in this case were the ingenuity, activity, creative imagina- tion and bold concepts of the many unnamed chemists, designers and entre- preneurs in the world who have fashioned great industries from our humble beginnings. If today I stand with my colleague Natta, who has been particularly effective in promoting this explosive wave, in the limelight of distinction, and do wish to manifest, with this address, my appreciation for the honor bestowed upon me, I must begin by thanking these many anonymous persons. They, too, deserve this distinction. The extent of this "explosion" may be illustrated by two charts 1, in which the location of newly-established plants is indicated. The places marked by black circles refer to the production of high molecular weight materials, the crosses to new production facilities which, though concerned with low mo- lecular weight materials, nevertheless also have some connection with the ad- dress I am delivering today (Figs. 1 and 2). The new development had its inception near the end of 1953, when I, to- gether with Holzkamp, Breil and Martina, observed-during only a few days of an almost dramatic course of events-that ethylene gas will polymerize very rapidly with certain catalysts that are extremely easy to prepare, at 100, 20 and 5 atmospheres and, finally, even at normal pressure, to a high molecular weight plastic. -
