α-Nitrocinnamic Nitriles in Reactions with 1-Methylpyrrole, Hydrazine, Phenylhydrazine, and o-Aminothiophenol
摘要
Abstract
The reaction of unsubstituted α-nitrocinnamic nitrile with 1-methylpyrrole ends with the formation of an AdN product, whereas the reactions of 2-aryl-2-nitroacrylonitriles with such N,N- and N,S-binucleophiles as hydrazine, phenylhydrazine, and o-aminothiophenol lead to transformation products of the initially formed adducts, linear azines and phenylhydrazones, or to a heterocyclic benzothiazole structure.
