Two equivalents of allenic nitrile or phenylpropynenitrile add to 1,2- and 1,3-diamines, 2-aminoethanethiol, ethanedithiol, and 4-aminopyridine to give 2:1 adducts of structure (2), (4), and (5).Ring closure and elimination of one equivalent each of allenic nitrile (or phenylpropynenitrile) and acetonitrile gave the imidazolines (29), the thiazolines (30), and the tetrahydropyrimidines (31).Mass spectral fission patterns are discussed.
