摘要
Highly regioselective homocoupling of N,N-dialkylanilines can be achieved in water with cerium reagents, in which various N,N,N′,N′-tetraalkylbenzidines are obtained from N,N-dialkylanilines either by direct oxidation by cerium（Ⅳ）reagents or by cerium（Ⅲ） reagents in the presence of hydroperoxide.
