Baddar, F. G. published the artcilePhenylpropiolic acids. IX. Reaction of arylpropiolic acids with hydrazine and phenylhydrazine, Computed Properties of 27412-71-1, the main research area is phenyl propiolic acid hydrazines; propiolic acid phenyl hydrazines; acid phenyl propiolic hydrazines; hydrazines phenyl propiolic acid; pyrazolones; azines aromatic.
Phenyl-, p-chlorophenyl-, and 3,4-methylenedioxyphenylpropiolic acids react with N2H4 to give, in each case, a mixture of the corresponding pyrazol-5-one and azine. p-Methoxyphenyl- and 3,4-dimethoxy-phenylpropiolic acids give azines only. Phenyl-, p-chlorophenyl-, and m-chlorophenylpropiolic acids react with PhNHNH2 to give the corresponding 5-aryl-1-phenylpyrazol-3-ones.
Journal of the Chemical Society [Section] C: Organic published new progress about phenyl propiolic acid hydrazines; propiolic acid phenyl hydrazines; acid phenyl propiolic hydrazines; hydrazines phenyl propiolic acid; pyrazolones; azines aromatic. 27412-71-1 belongs to class pyrazoles-derivatives, name is 5-Phenyl-1H-pyrazol-3(2H)-one, and the molecular formula is C9H8N2O, Computed Properties of 27412-71-1.
