Article abstract of DOI:10.1246/cl.1987.237

Reaction of 3,3-dimethyl-6-oxa-3-silabicyclo<3.1.0>hexane with N-benzyltriphenylphosphinimine yields 1,3-butadiene and 2,2,4,4-tetramethyl-6-vinyl-1,3-dioxa-2,4-disilacyclohexane (3).A mechanism for the formation of (3) which involves the reaction of dimethylsilanone <(CH3)2Si=O> with 2,2-dimethyl-4-vinylsilaoxetane is proposed.
