Abstract

Abstract The first preparations of C-unsubstituted stannacycloheptatriene and germacycloheptatriene analogues of cycloheptatriene, are described with their spectroscopic properties. A stannacyclohexadienyl anion derived from stannacyclohexadiene by treatment with lithium di-isopropylamide was allowed to react with chlorocarbene generated from dichloromethane and n-butyllithium, and this led to the ...
