Synthesis of 2-(4,5-Dihydrofuryl)- and 2-(Tetrahydrofuryl)dimethylhydrosilanes. Rearrangement of 2-(Tetrahydrofuryl)dimethylhydrosilane with Ring Expansion

Abstract

2-(4,5-Dihydrofury1)-and 2-(tetrahydrofuryl)dimethylhydrosilanes (I and 11) have been synthesized.The latter rearranges easily and quantitatively to 1-oxa-2-sila-2,2-dimethylcyclohexane in the presence of palladium catalyst.The possibility of hydrosilylation of alkenes and alkynes by I and I1 has been demonstrated.2-(4,5-~ih~drofury1)-and 2-(tetrahydrofury1)dimethylhydrosilanes have not been described in literature before.However, they may be useful for introduction of di-and tetrahydrofurylsilyl groups into unsaturated compounds by the hydrosilylation.
