1-Phenylpentafluoropropene and a number of its para- and ortho-substituted derivatives were prepared in high yields by reaction of hexafluoropropene with etheral solutions of corresponding phenylmagnesiumbromides in sealed glass tubes under autogenous pressure. The products were obtained as mixtures of the Z and E isomers, which ratios varied from 1/2 to 1/6 in favour of the E forms. 19F n.m.r. and
通过使六氟丙烯与相应的苯基溴化镁的醚溶液在自生压力下反应,可高收率地制备1-苯基五氟丙烯及其许多对位和邻位取代衍生物。获得的产物为Z和E异构体的混合物,其比率从1/2到1/6变化,有利于E形式。报道了1-苯基五氟丙烯的19 F nmr和ir光谱以及bp。
