Abstract

A few Fe–salan dimer complexes serve as catalysts for aerobic oxidative coupling (AOC) of 2-naphthols, but some others do not. X-Ray and cyclic voltammetry studies of various Fe–salan complexes revealed that the absence or the presence of double hydrogen bonding in Fe–salan dimers, the oxidation potential of monomeric Fe–salan species and the location of the resulting radical cation are critical factors for the catalytic activity of iron–salan complexes for the AOC.
