Preface Over the past decade boron has been accorded a treatment of which most of the other elements might well be envious. Acting on more or less qualitative indications that certain boron compounds held considerable promise as "superfuels" for jet craft and rockets, the Government of the United States invested many millions of dollars in a program of research and development which encompassed almost all aspects of boron chemistry.

    AN ABSTRACT OF THE THESIS OF James Maurice Self for the Ph. D. in Inorganic Chemistry (Name) (Degree) (Major) Date thesis is presented , ,7//,9/";= Title FLUOROBORANES. I. PREPARATION AND PROPERTIES OF TRIFLUOROMETHYLDI- n- BUTYLBORANE,, II. A STUDY OF DIBORON TETRAFLUORIDE Redacted for Privacy Abstract approved (Major professor¡ A large -scale preparative method for potassium di- n- butyl- borate in triethylamine solvent has been developed. The reaction of potassium di- n- butylborate I with trifluoromethyl iodide has been shown to yield trifluoromethyl di- n- butylborane and other products. Reaction of this substance with boron trifluoride gave trifluoromethyl boron difluoride. Reactions of diboron tetrafluoride, boron tri- bromide, and di- n- butylboron chloride with trifluoromethyl mercury iodide and bis(trifluoromethyl) mercury have also been studied. In each case a free radical mechanism leads to extensive decomposi- tion of the trifluoromethyl group. The design and operation of an all- glass, excepting the stain- less steel detector unit, gas chromatograph is given. The instrument was operative on both a preparative and analytical scale handling samples that range in size from less than 0.25 ml up to five ml. The experimental equipment and technique for the determination of the infrared spectrum of volatile compounds and compounds of mar- ginal stability is described. The apparatus and technique were used to determine the infrared spectrum of diboron tetrafluoride. FLUOROBORANES. I. PREPARATION AND PROPERTIES OF TRIFLUOROMETHYLDI - n- BUTYLBORANE, II.

    A Publication of Reliable Methods for the Preparation of Organic Compounds Working with Hazardous Chemicals The procedures in Organic Syntheses are intended for use only by persons with proper training in experimental organic chemistry. All hazardous materials should be handled using the standard procedures for work with chemicals described in references such as "Prudent Practices in the Laboratory" (The National Academies Press, Washington, D.C., 2011; the full text can be accessed free of charge at http://www.nap.edu/catalog.php?record_id=12654). All chemical waste should be disposed of in accordance with local regulations. For general guidelines for the management of chemical waste, see Chapter 8 of Prudent Practices. In some articles in Organic Syntheses, chemical-specific hazards are highlighted in red “Caution Notes” within a procedure. It is important to recognize that the absence of a caution note does not imply that no significant hazards are associated with the chemicals involved in that procedure. Prior to performing a reaction, a thorough risk assessment should be carried out that includes a review of the potential hazards associated with each chemical and experimental operation on the scale that is planned for the procedure. Guidelines for carrying out a risk assessment and for analyzing the hazards associated with chemicals can be found in Chapter 4 of Prudent Practices. The procedures described in Organic Syntheses are provided as published and are conducted at one's own risk. Organic Syntheses, Inc., its Editors, and its Board of Directors do not warrant or guarantee the safety of individuals using these procedures and hereby disclaim any liability for any injuries or damages claimed to have resulted from or related in any way to the procedures herein.
