Iron pentacarbonyl is an effective promoter for additions of halogenated acid esters and nitriles to pentafluorophenyl carbonyl compounds 1, 4, and 5 by the Reformatsky-type reaction and reductive coupling of compound 1. The electron-withdrawing character of the pentafluorophenyl group has a significant effect on the reaction pathway and the type of the reaction products. The reactions involving metal
五羰基铁是卤代酸酯和添加物的有效的启动子的腈以五氟苯基羰基化合物1,4和5由列福马茨基型反应和化合物的还原偶联1。五氟苯基的吸电子特性对反应途径和反应产物的类型有重要影响。涉及衍生自Fe(CO)5的金属络合物系统的反应具有许多优点,例如操作简单,无需使用无水溶剂和惰性气氛。已经提出了反应方案,并且优化了大多数产物的制备合成条件。
