Unsymmetrical α -diketones have been obtained via cross coupling of acyltins with acylhalides under PdCl2(PPh3)2 catalysis while symmetrical α -diketones have been readily obtained via “in situ” formation of acyltins using hexabutylditin and acyl chlorides under similar experimental conditions.

Silylation of acyltins provided a new class of polyfunctional compounds containing vinyltin and silyl enolate groups. The protected acyl moiety could be selectively transferred to various electrophiles via a palladium-catalyzed process.
