Chemoselective cross-coupling of aliphatic and aromatic acyl chlorides with organostannanes provides a useful alternative to Friedel-Crafts acylations for the synthesis of ketones. A range of ketones are obtained in high yield using 2.5 mol % of bis(di-tert-butylchlorophosphine)palladium(II) dichloride as precatalyst. The catalyst tolerates various functional groups including aryl chlorides and bromides that usually undergo oxidative addition to palladium complexes.
