Solid Propellant Additives from Pentaborane-9.
Abstract
The electrochemical behavior of pentaborane-9 and its reactivity with acetylenic halides were studied. Although pentaborane-9 is itself not electro-active it does react with other electrochemically generated species. It was found that methyl iodide, iodobenzene, chromium hexacarbonyl, dimanganese decacarbonyl, and iron pentacarbonyl generated electroactive species that reacted with pentaborane-9. The reaction of pentaboryllithium and propargyl chloride and with 1-4-dichlorobutyne-2 yielded mixtures of nidocarborane polymers and some higher boranes. The propargyl chloride reaction product reacted with anhydrous cobaltous chloride and cyclopentadienyllithium to give a mixture of cobaltaboranes and cobaltacarboranes which were not separable. An attempt was made to prepare phenylpentaborane but the product could not be isolated. (Author)
