Application of a dimeric P,C-palladacycle complex as a catalyst in Suzuki and Heck cross-coupling reactions

In this Letter the dimeric palladacycle [Pd(μ-C1)(P (OPh)2(OC6H4)]2 containing a phosphorus donor atom is prepared and its catalytic activity was tested in the Suzuki reaction of phenylboronic acid at room temperature, and the Heck reaction of styrene at 130 °C with aryl halides of varying electron density. All reactions were monitored by GC and generally gave high yields of coupled products.
