New activating agents, 3,3′-(phenylphosphinylidene)bis[2(3H)-benzoxazolone] (4) and 3,3′-(phenylphosphinylidene)bis[2(3H)-benzothiazolone] (5), were readily prepared by the reaction of phenylphosphonic dichloride (3) with 2(3H)-benzoxazolone (1) and 2(3H)-benzothiazolone (2) respectively in the presence of triethylamine at room temperature. The new activating agents 4 and 5 were found to be useful
新的活化剂 3,3'-(苯基亚膦基)双 [2(3H)-苯并恶唑酮] (4) 和 3,3'-(苯基亚膦基)双[2(3H)-苯并噻唑酮] (5) 可以通过以下方式轻松制备在室温下,在三乙胺存在下,苯基膦酰二氯 (3) 分别与 2(3H)-苯并恶唑酮 (1) 和 2(3H)-苯并噻唑酮 (2) 反应。发现新的活化剂 4 和 5 可用于在温和条件下制备酰胺、酯和二肽。此外,间苯二甲酸与芳族二胺在吡啶存在下使用活化剂 4 的直接缩聚反应在室温下快速进行,以产生特性粘度高达 0.80 dL/g 的聚酰胺。
