An efficient catalytic route to biaryls by employing (generally) only 0.25 mol % of Pd(OAc)<sub>2</sub> and 0.5 mol % of <b>1</b> 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)<sub>2</sub>/<b>1</b> loadings.
