Abstract

Carbostannylation of 1, 2-dienes using acyl-and alkynylstannanes was achieved by means of nickel catalysis. In particular, acylstannylation of 1, 2-dienes could be carried out with bis (1, 5-cyclooctadiene) nickel [Ni (cod) 2] and acylstannanes to give selectively α-acylmethyl (vinyl) stannanes. The reaction was also applicable to acylstannanes prepared in situ by protonolysis of α-alkoxyalkenylstannanes or by reactions of α-silyloxyvinylstannanes with ...
