Acyl Migrations on 3(5)-Amino-pyrazole

Graubaum, Heinz

, p. 585 - 588 (1993)

3(5)-Amino-pyrazole 1 form 3 isomeric monoacylation products, 4-diacylation products and 3-triacylation products by reaction with electrophiles like cyanates, isocyanates or carboxylic and chlorides, respectively.Acyl migrations are observed depending on the reaction temperature and the structure of the acyl residue.The structures of the acyl derivatives of 3(5)-amino-pyrazole were characterized by nmr-spectroscopy.
