Abstract

Copper (II) Schiff base complexes of 2-(1-phenylethyl imino) methylphenol (3), methyl-N-(2-hydroxyphenyl)-l-serine (4) and methyl-N-(2-hydroxyphenyl)-l-tyrosine (5) were found to be an efficient catalyst for the aerobic oxidative coupling of 2-naphthols to binaphthols. Among the various copper (II) Schiff base complexes, the complex 3 was found to be the most reactive for this transformation.
