ABSTRACT:
Phosgene iminium chloride has been used as a reagent in a variety of reactions to produce compounds useful in the preparation of organic conductors, inorganic complexes, and heterocyclic compounds. This reagent undergoes expedient reactions with either H.sub.2 Se or H.sub.2 S. Of particular interest is a synthetic process beginning with the production of dichalcogen carbamate by the reaction of phosgene iminium chloride with, for example, H.sub.2 Se followed by subsequent processing steps to produce tetramethyl tetraselenafulvalene.
