Preparation, Structure, and Color of 4-- and 4--1H-pyrazol-5(4H)-ones

(Dicyanomethylene)pyrazolones 1a, b are treated with some indoles and pyrroles.The resulting disubstituted malono-nitriles 2a-f, 4a-e, 6 yield cyanomethylene compounds 3a-f, 5a-e, 7 by irreversible thermal or photochemical decomposition.The compounds exist in different isomeric forms.Structures are proven by NMR spectroscopy and X-ray analysis.UV-Vis data are discussed by means of AM1 and INDO/S-CI calculations. Key Words: Calculations, AM1 and INDO, S-CI / Cyanomethylene compounds / Pyrazolones
