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.

Heterocycles containing one or two atoms of oxygen are synthesized by the condensation of pyridine carboxaldehydes with ethylene glycol, 1,3-propanediol, and 3-methyl-3-buten-l-ol. When the unsaturated alcohol is used, linear acetals are formed along with the cyclic products. Pyridine and oxygen-c
