Abstract

The reaction of p-substituted benzyl bromides with the >P--O- ions inTHF, alcohols and toluene as the solvents is described. According to the reduction potential of the p-substituted benzyl bromides and the solvent used the formation of the P-C bond, debromination and/or dimerization occur. The principal process is believed to be X-philic substitution, the dimers are formed through a secondary process via SET from the p-substituted benzyl anions into the p-substituted benzyl bromides.
