New 1,10-Phenanthrolinethioles

Abstract

Reaction of KHS with 2-chloro-and 2.9-dichloro-1,lO-phenanthroline in ethanol at elevated temperature and pressure afforded the corresponding phenanthrolinethiols which were characterized by spectroscopic and chemical methods. 2.2'-Thiobis(1,lO-phenanthroline) and other heteroaryl sulfides derived from 1,lO-phenanthroline-2-thiol were prepared by amide promoted nucleophilic substitution of aryl halide by thiolate anion.
