Palladium catalyzed coupling reaction of acylchromate complexes and allylic bromides

Article abstract of DOI:10.1246/cl.1999.309

A cross-coupling reaction between acylchromate complexes and allylic bromides takes place under CO atmosphere in the presence of a catalytic amount of Pd(PPh₃)₄ to afford the corresponding allylic ketones in good yield. The same reaction also proceeds by adding RNC under argon atmosphere in place of CO atmosphere. Thus, the acylchromate complex works as a good acyl donor for Pd catalyzed acylation reaction.
