Abstract : Autoxidation of methylboranes (CH3)3B, (CH3)- 4B2H2, 1,1-(CH3)2B2H4 and of diborane was investigated at cryogenic temperatures in solution. Trimethylborane was the only compound susceptible to oxidation, yielding a coordination polymer. Depolymerization to the monomeric dimethylborylmethylperoxide occurs at very low temperatures. The mechanism of oxidation is discussed. Nitrosyl nitrate, a metastable isomer of dinitrogen tetroxide, has been found to be unexpectedly reactive toward some diolefins. Dinitro compounds and nitroso nitrates are formed even at -196 C. A low temperature infrared cell, incorporating a horizontal sample compartment, and utilizing a vertical optical beam, has been designed and constructed. It will be used for in situ spectroscopic investigation of reactions at low temperatures. The vacuum line work on the oxidation of methylboranes was completed and the results are incorporated in the report in the form of a manuscript for publication. Work on oxidative nitration, and in low temperature spectroscopy is continuing and the accomplishments to date are presented as a descriptive discussion. (Author)
