摘要:
以水溶性RuCl2(TPPTS)2 [TPPTS: P(m-C6H4SO3Na)3]为催化剂，研究了表面活性剂存在下水–有机两相体系中苯乙酮的催化氢转移反应。结果显示双长链阳离子型表面活性剂的加入，能够显著提高目标反应的转化率，同时这一反应体系使产物与催化剂的分离过程简化，有利于催化剂的循环使用，实验证实在这样的条件下，催化剂循环使用十次活性没有明显下降。Transfer hydrogenation of acetophenone catalyzed by water-soluble ruthenium complex, RuCl2 (TPPTS)2 [TPPTS: P(m-C6H4SO3Na)3], in the presence of surfactants, was studied. The results showed that the reaction was obviously accelerated by double long-chain cationic surfactants. This was attributed to the formation of vesicles. In this vesicle system, the separation of catalyst and product is simplified after reaction, and the catalyst could be reused for at least 10 times in high conversion.
