New Synthetic Applications of Aryllead Triacetates. N-Arylation of Azoles

Article abstract of DOI:10.1021/jo00122a060

Treatment of a variety of azoles or their anions with p-tolyllead triacetate in the presence of copper(II) acetate afforded the corresponding N-aryl derivatives, normally in excellent yields.Room temperature arylation of an aminobenzimidazole derivative was chemoselectively directed to the amino group.
