The addition of perfluoroalkyl halides RfX (1) (X=I, Br) to ethyl propiolate (2) has been performed smoothly with zinc powder and a catalytic amount of bromo(pyridine)cobaloxime(III) (3) in ethanol. The product (4) was a mixture of Z- and E-isomers, with the former predominating.
用锌粉和在乙醇中催化量的溴(吡啶)钴氧肟(III)(3)平稳地将全氟烷基卤化物R f X(1)(X = I,Br)添加到丙酸乙酯(2)中。产物(4)是Z-和E-异构体的混合物,其中前者占主导地位。
