Abstract

A series of electronically tuned trans-[CoIII (chel)(CH2Cl)] 2 complexes, where chel is a salen derivative (salen= 2, 2′-ethylenebis (nitrilomethylidene) diphenol) containing either two or four methyl substituents in different positions, has been synthesized and characterized, both in solution and in the solid state. These complexes undergo an intramolecular cyclization reaction in methanolic solution to form the corresponding cis β ...
