organozincate of composition Et3ZnLi and di-tert-butyl ketone react in toluene to form (after hydrolysis) ethyl-di-tert-butylmethanol. The rate is proportional to approximately [Et3ZnLi](-0.5)[ketone](1) when the initial concentration of Et3ZnLi is greater than that of the ketone but proportional to [Et3ZnLi](1)[ketone](-1) when the initial concentration of ketone is greater than that of Et3ZnLi. The rate
组成为Et3ZnLi的有机锌酸盐与二叔丁基酮在甲苯中反应形成(水解后)乙基二叔丁基甲醇。当Et3ZnLi的初始浓度大于酮的初始浓度时,该比率大约与[Et3ZnLi](-0.5)[酮](1)成正比,而当Et3ZnLi的初始浓度大于[Et3ZnLi](1)[酮](-1)时,则成正比。酮的初始浓度大于Et3ZnLi。Et3ZnK向二叔丁基酮中的添加速率小于Et3ZnLi的10(-4)。
