Palladium-catalyzed Coupling of Benzoyl Halides with Aryltrifluorosilanes Leading to Diaryl Ketones

Acyl–aryl Hiyama coupling of acyl halides with arylsilanes has been achieved by employing a palladium/phosphine catalyst system. A variety of acyl chlorides and fluorides can be applied for coupling with arylsilicon reagents, and unsymmetrical benzophenone derivatives can be prepared using this protocol.
