Abstract
A cross-coupling reaction between air- and moisture-stable aryl- or alkyl(triorgano)silanes and aryl tosylates was developed by cooperative palladium/copper catalysis. In order to obtain the coupling products in high yields, the presence of the P,N-heterobidentate ligand 1-[2-(dicyclohexylphosphanyl)phenyl]-N,N-dimethylmethanamine (L1) is crucial. This protocol tolerates a variety of functional groups such as acetyl, cyano, chloro, formyl, and alkoxycarbonyl moieties.
