The trifluoromethyl group of certain compounds containing one or two trifluoromethyl groups can be converted to the carbomethoxy group by treatment with sodium methoxide followed by aqueous acidic work-up. α-Trifluoromethyl esters can be obtained by selective methanolysis of the 1,1,1,3,3,3-hexafluoroisopropyl group in some cases. The structural requirements for the transformation are delineated, and
某些含有一个或两个三氟甲基的化合物的三氟甲基可通过用甲醇钠处理然后进行酸性水溶液后处理而转化为碳甲氧基。在某些情况下,可以通过1,1,1,3,3,3-六氟异丙基的选择性甲醇分解获得α-三氟甲基酯。描绘了转变的结构要求,并且机械研究证实了所提出的机理,即脱氟化氢-加成-消除过程。
