摘要

Tetradentate organosulphur ligands are efficiently prepared by the selective reduction of biddithiolanes) with two ... The use of disulphide dithiols (4) as tetradentate ligands for a variety of metal ions is well established.l.2 Compounds of this type, and ligands derived from them, have been used as models of the copper binding site of the 'blue' proteins.3 and as precursors to polythiomacrocyclic compounds.4 We report herein a convenient, high yield procedure for the preparation of a ...
