Abstract

The synthesis and structural assignments of 9-chloro-1, 1-phenanthroline-2 (1H)-thione and 1, 10-dihydro-1, 10-phenanthroline-2, 9-dithione have been accomplished. The sulfur- bridged bis-1, 10-phenanthroline macrocycle was readily prepared by heating the thione or equimolar amounts of the dithione and 2, 9-dichloro-1, 10-phenanthroline in diphenyl ether. Displacements of 2-chloro-or 2, 9-dichloro-1, 10-phenanthroline with N, N- ...
