Abstract

We report a facile two step synthesis of chiral tetradentate ligands for late metal complexes. The ligands are easily prepared from trans-1, 2-diaminocyclohexane or chiral 1, 2- diphenylethylenediamine and a heteroaromatic sulfonyl chloride in the presence of base (K2CO3 or Et3N). These compounds represent a new class of chiral tetradentate N2S2 and N4 based ligands.
