研究了十二烷基硫酸盐和十二烷磺酸盐作为刘易斯酸-表面活性剂复合催化剂存在下，水相中Aldol和Diels-Alder反应。在羟醛缩合反应中，这些盐在反应初始阶段的催化能力和羟醛缩合产物的最终产率方面彼此不同，而这些盐不影响Diels-Alder反应的反应速率。这些结果揭示了刘易斯酸在水中催化的显著特征。(C)1999 Elsevier Science Ltd.保留所有权利。
Aldol and Diels-Alder reactions in water in the presence of various dodecyl sulfate and dodecanesulfonate salts as Lewis acid-surfactant-combined catalysts have been studied. In the aldol reactions, these salts differed from each other with respect to their catalytic ability at the initial stage of the reaction and to the final yields of the aldol product, while these salts did not affect the reaction rates of the Diels-Alder reactions. These results disclose the remarkable characteristics of Lewis acid catalysis in water. (C) 1999 Elsevier Science Ltd. All rights reserved.
