fluorine-containing benzimidazoles were obtained by the reaction of o-phenylene-diamine, 3,4-diaminotoluene, and 1,2-diamino-4-chlorobenzene with hexafluoropropene or perfluoro(methyl vinyl ether) in DMF. A new efficient method of synthesis of 2-(1,2,2,2-tet-rafluoroethyl)benzimidazole by the reaction of o-phenylenediamine with hexafluoropropene in the presence of diethylamine or dimethylamine in ethyl acetate is developed
通过邻苯二胺、3,4-二氨基甲苯和1,2-二氨基-4-氯苯与六氟丙烯或全氟(甲基乙烯基醚)在DMF中反应得到各种含氟苯并咪唑。开发了一种新的有效合成2-(1,2,2,2-四氟乙基)苯并咪唑的方法,在乙酸乙酯中,在二乙胺或二甲胺存在下,邻苯二胺与六氟丙烯反应。
