Triphenylphosphine dibromide (TPPDB) has been found to be a very effective catalyst for the one pot three-component Mannich reactions of aryl aldehyde, acetophenone, and benzyl carbamate under solvent-free condition at room temperature. The advantageous features of this methodology are operational simplicity, shorter reaction time, cost-effectiveness, and excellent yields. The catalyst possesses distinct
在室温下,无溶剂条件下,三苯基膦二溴化物(TPPDB)是一种非常有效的催化剂,用于芳基醛,苯乙酮和氨基甲酸苄酯的一锅三组分曼尼希反应。该方法的优点是操作简单,反应时间短,成本效益好和产率高。与用于该转化的其他催化剂相比,该催化剂具有明显的优点。
