Abstract

The reaction of tributyltin enolates, prepared from tributyltin methoxide and enol acetates in situ, with bromobenzene in the presence of a catalytic amount of PdCl2 (o-tolyl3P) 2 was found to give α-phenyl ketones in good yields with essentially complete retetion of the acetate regiochemistry.
