α-Alkoxytin compounds in organic synthesis: an efficient synthesis of α-ethoxyalkenyl- and α-ethoxyalkynyl-tin compounds

Abstract

Alkenyl- and alkynyl-aluminium reagents react with diethoxymethyltributyltin to afford the corresponding α-ethoxyalkenyl- and α-ethoxyalkynyl-tin compounds in high yields; the but-3-ynyltin derivatives has been modified to give new bis(tributyltin) precursors useful for selective organic synthesis.
