Gold(I) complexes react with 4-allenyl arenes in an exo fashion to furnish vinyl-substituted benzocycles. Phosphite gold(I) monocations were found to be optimal, and the catalyst was tolerant of ethers, esters, and pyrroles. Reactions proceeded in unpurified solvent at room temperature.
金(I)配合物以外型方式与4-烯丙基芳烃反应,生成乙烯基取代的苯并环。发现亚磷酸金(I)单阳离子是最佳的,并且该催化剂对醚、酯和吡咯具有耐受性。反应在室温下于未纯化的溶剂中进行。
