SYNGAS REACTIONS II. THE HOMOGENEOUS CATALYZED CARBONYLATION AND CYCLIZATION OF ALLYLIC SUBSTRATES

Article abstract of DOI:10.1016/S0022-328X(00)82815-6

Carbon monoxide insertion and/or addition to allylic precursors may lead to the formation of both linear and cyclic carbonylation products.In examining these competing reaction paths, rhodium, platinum, palladium and nickel-based homogeneous catalysts have been developed which are particularly useful for the selective synthesis of γ-butyrolactam, N-alkyl-2-pyrrolidones, vinylacetate and phenylacetate esters and diesters from a variety of allylic and benzylic substrates.The extension of this catalysis to the carbonylation of certain vinylic and propargyl congeners hasalso been considered.
