A facile route to the synthesis of 1,1'-binaphthyl-4,4'-diamines (naphthidines) and 1,1'-binaphthyl-2,2'-diamines (BINAMs) was developed by the oxidative homocoupling of 1- and 2-naphthylamines, respectively, using FeCl(3) as oxidant and K(2)CO(3) as base in 1,2-dichloroethane under ambient conditions. A preliminary mechanistic investigation was performed by the ESR spectroscopy and intermediate-trapping technique.

it is desirable to develop a general and mild synthetic approach to diverse biaryl diamines. Oxidativecoupling is an efficient and promising strategy for the synthesis of these targets. We have now developed a direct formation of biaryl diamines by oxidativecoupling using a hypervalent iodine(III) reagent.
