Metal-catalysed exchange of alkyl and silyl hydrogen in organosilanes with tritium gas over Raney nickel as measured by ³H N.M.R

Abstract

Analysis by tritium n.m.r, of triethylsilane, tetramethylsilane, hexamethyldisiloxane and chlorodimethylsilane exchanged with tritium gas over Raney nickel at 100°C shows that exchange readily occurs in alkyl substituents as well as with silyl hydrogen; novel species involving charge-transfer intermediates in dissociative adsorption at the C-H as well as the Si-H bonds are proposed to explain the data.
