本文报告了对羟基苯乙酮克莱门逊还原作用的反应动力学,从大量实验结果出发,论述了它的机制。认为Steinkopf等提出的反应机制(醇类是克莱门逊还原的中间体)是不正确的,Brewster′提出的在反应过程中形成有机金属碳离子是比较合理的。作者根据动力学研究结果,并吸取了Brewster假设中的一些特点认为机制是:羰基化合物在氯离子帮助下和锌发生 This paper reports the kinetics of the cleavage reduction of p-hydroxyacetophenone. From a large number of experimental results, its mechanism is discussed. It is believed that the reaction mechanism proposed by Steinkopf et al. (Alcohol is an intermediate of Clementon reduction) is not correct. It is reasonable that Brewster ’proposed to form organometallic carbon ions during the reaction. Based on the kinetic results and taking into account some of the features of the Brewster hypothesis, the authors consider the mechanism as follows: carbonyl compounds are generated with the help of chloride ions and zinc
