Chemistry of α-Amino Nitriles. Exploratory Experiments on Thermal Reactions of α-Amino Nitriles
The paper extends a previously published report on chemical properties of α-amino nitriles and of members of the C3H4N2 ensemble (Scheme 1) as observed in experiments carried out under non-aqueous conditions.The reactions investigated and the observations made are summarized in some detail in the English footnotes (*) referring to Schemes 1-17 and Fig. 1.

PHOTOCHEMICAL CONVERSION OF PYRAZOLES TO ENAMINONITRILES AND IMIDAZOLES
Irradiation of pyrazole, 1-methylpyrazole and 4-cyano-1-methylpyrazole gave 3-aminoacrylonitrile, 3-methylaminoacrylonitrile and 2-cyano-3-methylaminoacrylonitrile along with corresponding imidazoles.A new pathway is proposed in which both enaminonitrile and imidazole are produced immediately from pyrazole, besides the sequence of pyrazole - enaminonitrile - imidazole.
