1-hydroxy-1H-perfluorooctyl compound (4), which was supposed to be formed by the reduction of 3. A similar reaction of 2,2,2-trifluoroacetophenone with tert-butyllithium did not gave any reduction product. Detailed investigation showed that lithium ethoxide worked as the reducing agent of this abnormal reduction. By the reaction of lithium isopropoxide, an aldol product from 2,2,2-trifluoroacetophenone with acetone
的反应叔丁基ñ - (2-溴苯基)氨基甲酸叔丁酯(1用乙酸乙酯全氟辛在存在下)叔丁基锂没有得到所需Ñ - (2- perfluorooctanoylphenyl)氨基甲酸酯(3),但是,得到1-羟基-1H- -全氟辛基化合物(4),推测是通过3的还原而形成的。-2,2,2-三氟苯乙酮用类似的反应叔丁基锂没有得到任何还原产物。详细的研究表明,乙醇锂是这种异常还原的还原剂。通过异丙醇锂的反应,分离了由2,2,2-三氟苯乙酮与丙酮形成的醇醛产物,而该醇盐以高产率还原了全氟庚基或全氟丙基苯基酮,而没有形成醇醛加合物。
