## Abstract Tetraazathiapentalene derivative 1 reacts with heterocumulenes such as diphenylketene (2) and 2βpyridylisothiocyanate (5) to give heterocycles 3, 6 and 7 with elimination of methylisothiocyanate. The reactions of thiadiazolopyrimidine derivatives 8aβb with ethoxycarbonyl isothiocyanate
Novel Ni(C0)4-promoted tandem cycloadditions of diphenylcyclopropenone to isothiocyanates and to CS2 were found to provide new heterocyclic spirans, pyrroline-2-one-5-Spiro-5 '-thiolene-4'-ones and a thiolene-2-one-5-spiro-S'-thiolene-4'-one, respectively, in moderate yields.
