The reaction of pentafluoroacetanilide hydrodefluorination under the action of zinc in the presence of catalytic amounts of complexes, generated in situ from nickel chloride and 2,2′-bipyridine or 1,10-phenanthroline, was studied. The influence of the solvent, catalytic complex, and substrate : zinc molar ratio on the reaction course was investigated. On the basis of the results obtained, preparative methods for the synthesis of 3,4,5-trifluoro- and 2,3,4,5-tetrafluoroanilines were developed.
在在位生成的镍氯化物与2,2'-联吡啶或1,10-菲啰啉形成的催化复合物的作用下,研究了五氟乙酰苯胺的氢去氟化反应。研究了溶剂、催化复合物和底物与锌的摩尔比对反应过程的影响。根据获得的结果,开发了合成3,4,5-三氟和2,3,4,5-四氟苯胺的制备方法。
