Nickel-catalysed acylstannylation of 1,2-dienes: synthesis and reactions of α-(acylmethyl)vinylstannanes
Abstract
Bis(cycloocta-1,5-diene)nickel was found to be an effective catalyst for the acylstannylation of 1,2-dienes to give a wide variety of α-(acylmethyl)vinylstannanes, which were transformed to variously substituted conjugated and unconjugated enones by carbon–carbon bond forming reactions.
