Aryl chlorides are efficiently cross-coupled with aryl boronic acids using 0.25 mol% of 4,4'-dichlorobenzophenone oxime derived palladacycle as precatalyst in the presence of I mol% of [HP(t-Bu)(3)]BF4 as ligand, K2CO3 as base, TBAOH as additive, and DMF as solvent under conventional thermal or MW irradiation conditions. Under these simple reaction conditions a wide array of deactivated and hindered aryl chlorides react cleanly to afford in high yields functionalized biaryl derivatives.
