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, and alkoxides.
