近年来,随着β,β-二氟乙烯基类化合物的广泛应用,其合成方法的研究也越来越多.详细介绍了卤代二氟醋酸盐、卤代二氟甲烷、双膦酸盐、有金属参与、双三氟甲基汞和二异丙基胺基锂和二氟甲基芳环砜等法制备β,β-二氟乙烯的研究进展,同时对其反应机理作了相应阐述. In recent years, with the extensive application of β, β-difluorovinyl compounds, more and more studies have been devoted to the synthesis of these compounds.Hydrodifluoroacetates, halodifluoromethane, bisphosphonic acid Salt, metal participation, bistrifluoromethylmercury and lithium diisopropylamide and difluoromethyl arylcyclohexyl sulfone and other methods of preparation of β, β-vinylidene fluoride research progress, at the same time its reaction mechanism was made Explain.
