1,3-Thiazoline-2-thione-4,5-dithiolato, an efficient building block towards functionalized dithiadiazafulvalenes

A simple and efficient approach to N-methyl-1,3-thiazoline-2-thione-4,5-dithiolate, easily isolated as its zinc dithiolene complex, has been developed. The reactivity of this dithiolene complex as a nucleophilic dithiolate synthon and as a precursor of the air sensitive electron rich olefine, the bis ethylenedithiodithiadiazafulvalene (BEDT-DTDAF), is also described.
