2-Dimethylaminomethyl-3-trimethylsilylmethylbuta-1,3-diene as a synthetic equivalent of 2,2′-biallyl zwitterionic species

Abstract

The title compound reacts with nucleophiles followed by electrophiles in tandem or in the reverse order smoothly to give 1,2-dimethylenecyclohexanes and their oxa analogues; thus this reagent acts as the synthetic equivalent of 2,2′-biallyl zwitterionic species.
