Abstract
AbstractThrough free‐radical trapping experiments we have established, for the first time, the combination of arylhydrazines with o‐iodoxybenzoic acid (IBX) for the generation of aryl free radicals. On the basis of this finding, a method was developed for the N‐arylation of aromatic amines under mild conditions (base‐free, –5 °C) by using arylhydrazines as the arylating counterpart and arylamines. The scope of this method was demonstrated by using a number of arylhydrazines and arylamines, which gave the N‐arylated amines in good yields.
