title: What factors influence the catalytic activity of iron-salan complexes for aerobic oxidative coupling of 2-naphthols?
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.
