Abstract
An improved palladium-catalyzed Hiyama cross-coupling reaction is reported. In the presence of PdCl 2 (MeCN) 2 , P(o-tol) 3 and TBAF, a number of ArX (X = I, Br, Cl) were coupled with ArSi(OMe) 3 efficiently to afford the desired cross-coupled products in moderate to excellent yields. It is noteworthy that this protocol is conducted under relatively low Pd loadings and solvent-free conditions.
