Abstract

Abstract Monoalkyltrialkynyl-and dialkyldialkynyltin compounds can be selectively synthesized by transmetalation of tetraalkynyltin compounds with Grignard reagents; an example is given in Equation (1). This reaction provides a route to mono-and dialkyltin compounds that avoids the use of strongly electrophilic reagents. The labile tin–alkynyl bonds allow the transmetalation products to be converted into alkyltin oxides, chlorides, ...
