摘要

An efficient catalytic route to biaryls by employing (generally) only 0.25 mol% of Pd (OAc) 2 and 0.5 mol% of 1 in the Hiyama coupling reaction is reported. High yields for electron-rich,- neutral, and-deficient aryl chlorides are obtained. A variety of phenylsiloxanes undergo coupling with aryl bromides and chlorides with low Pd (OAc) 2/1 loadings.
