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 FeCl3 as oxidant and K2CO3 as base in 1,2-dichloroethane under ambient conditions. A preliminary mechanistic investigation was performed by the ESR spectroscopy and intermediate-trapping technique.
