New Sulfur Containing Titanacycles

Titanocenedicarbonyl, Cp2Ti(CO)2, activates the sulfur-sulfur bond in organic disulfides and sulfur homocycles like S6S7 and S8- Cyclic disulfides form chelating ligands with sulfur atoms attached to the Ti atom. The reaction with S6 yields a new compound with an eight sulfur atoms containing ligand. The novel titanocene compounds have been used as precursors for the synthesis of a series of methylene polysulfides.
