1-Chlorodifluoromethyl- and 1-trifluoromethyl-substituted 2-methylbenzimidazoles and benzotriazoles were obtained by chlorination of the corresponding methyl 1-azoledithiocarboxylates and subsequent fluorination of the resulting 1-trichloromethyl derivatives. The condensation of N-sodium salts of 2-alkylbenzimidazoles and indazole with CF2Br2 was shown to afford the corresponding 1-bromodifluoromethylated
通过氯化相应的1-唑二硫代羧酸甲酯,然后将所得的1-三氯甲基衍生物氟化,得到1-氯二氟甲基和1-三氟甲基取代的2-甲基苯并咪唑和苯并三唑。显示2-烷基苯并咪唑和吲唑的N-钠盐与CF 2 Br 2的缩合得到相应的1-溴二氟甲基化的化合物。
