Abstract

Aryl chlorides are efficiently coupled with aryl boronic acids using ligandless Pd/C in water. The catalyst is easily recovered via filtration and reused up to four times with an overall yield of 73%. In addition the catalytic activity and selectivity of a variety of homogeneous and heterogeneous palladium sources have been compared.
