2-functionalised vinylstannanes (E)/(Z)-Ph3SnCR′CHYRn with acetic and chloroacetic acid in CDCl3 proceeded by protodestannylation yielding Ph3SnOOCCH2X (X=H, Cl) and CHR′CHYRn. The results of kinetics measurements reveal that Lewis-basic substituents YRn facilitate the electrophilic cleavage of SnC bonds, and this effect increases with the basicity of the heteroatom Y, i.e. in the order S
