  • Reactions of organoboranes

    Thompson, Thomas Myron
    Abstract:
    An examination was made of some reactions involving a transfer of carbon from boron to carbon. In the case of the reaction of a C[subscript n] alkylorganoborane with dichlorocarbene the intermediate was a C[subscript n]₊₁ chloroalkylorganoborane. Oxidation of this intermediate yielded an homologous acid (33%) and the usual alcohol (66%)....

    Abstract:
    Steroid organoboranes have been found to be useful synthetic intermediates. Attempted pyrolyses, based on simple trialkylborane cyclizations, have not yielded C-19 or C-18 functionalized steroids, but have produced isomerized systems not otherwise available. Thus, hydroboration of cholesterol followed by pyrolysis at 215° gives 31% of 2-cholestene-6α-ol and 49% of a...
