Abstract

The influence of the substituents on the phenol on the regiochemtstry of the arylation reactions with Ph3BiCl2 and other bismuth reagents has been studied. O-Phenylation occurs with phenols substituted with electron-withdrawing groups. Electron-donating substituted phenols undergo ortho C-phenylation. Oxidative dimerisation has been observed with 2, 6-dialkyl phenols.
