摘要：

An efficient synthesis of biaryls using a Hiyama reaction between aryl iodides and aryltrialkoxysilanes in the presence of a diphenylphosphinomethylpolystyrene-supported palladium catalyst is described. The cross-coupling proceeds in the presence of only 0.1 mol % of supported palladium. The catalyst can be used at least four times and the palladium leaching is extremely low (ca. 1% of the initial amount). (C) 2012 Elsevier Ltd. All rights reserved.
