Project Description

There is currently much interest in nitrogen-rich ligands both as intriguing species in their own right and as potential high energy density materials. We suspect that unusual nitrogen-containing rings and chains might best be prepared in the coordination sphere of transition metals. The compound dithizone, PhN=NC(=S)NHNHPh, known for years as an analytical reagent, forms a cyclic mesoionic tetrazole thione (PhNN)2C=S when oxidized. Previous work in our lab has studied the reactions of thiones with various organometallic complexes and shown that processes involving dimerisation by loss of sulfur, C=S bond cleavage, and opening of heterocyclic rings are all possible. We therefore expect that when treated with an appropriate organometallic complex, the tetrazole thione ring will serve as the source for a variety of novel nitrogen-containing ligands.
This project is primarily organometallic chemistry with some organic synthesis.
