Reactions of monosilylarsine with some boron Lewis acids and the reaction of monosilylphosphine with boron tribromide

Abstract

The reactions of monosilylarsine with diborane, monobromodiborane, boron trichloride, and boron tribromide are discussed together with the reaction of monosilylphosphine with boron tribromide. Definite adducts are formed in all the reactions except that of diborane in which condensation to trisilyarsine occurs. A mechanism is suggested for this condensation and for the apparently anomalous reactions with boron tribromide.
