We have reported the Grignard reaction of Halothane, 2-bromo-2-chloro-1,1,1-trifluoroethane (1), with ketones gave unexpected products, α-(1-bromo-1-chloro-2,2,2-trifluoroethyl)alcohols (4) at a low temperature. However, this reaction hardly proceeded with aldehydes. Now, we found the reaction of 1 with aldehydes in the presence of zinc gave not only products of type 4, but α-(1-chloro-2,2,2-trifluoroethyl)alcohols
我们已经报道了氟烷,2-溴-2-氯-1,1,1-三氟乙烷(1)的格氏反应与酮的反应产生了意外的产物α-(1-溴-1-氯-2,2,2 -三氟乙基)醇(4)在低温下。但是,该反应几乎不与醛一起进行。现在,我们发现1在锌的存在下与醛的反应不仅得到4型产物,而且还产生了预期的产物α-(1-氯-2,2,2-三氟乙基)醇(3),在温和条件下以高至中等的产量。
