This patent describes a method of reduction of a silicon-halogen bond of a halodisilane to a silicon-hydrogen bond. Each halogen of the halodisilane is independently selected from the group consisting of fluorine, chlorine, bromine, and iodine, and wherein when there are two or more different halogens present, the halogen with the highest atomic weight is preferentially reduced by contacting the halodisilane with a trialkyltin hydride or dialkytin dihydride of the formula R{sub 3}SnH or R{sub 2}SnH{sub 2}, respectively, wherein R is an alkyl group containing 1 to 10 carbon atoms.
