Abstract

An 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 of addition of Et3ZnK to di-tert-butyl ketone is <10(-4) that of Et3ZnLi.
