Improved protocol for Thorpe reaction: Synthesis of 4-amino-1-arylpyrazole using solid-liquid phase-transfer conditions

Solid-liquid phase-transfer conditions were employed for the first time in the Thorpe reaction to synthesize 4-amino-1-aryl-3,5-substituted-1H-pyrazoles 3. Aryl amines were diazotized and coupled with various active methylene compounds such as cyano aceta

13C N.M.R. Examination of Ethyl Cyano(arylhydrazono)acetates

The products of the condensation of aryldiazonium salts with ethyl cyanoacetate are the (Z)- and (E)-isomers of the hydrazono forms.These have been examined separately by 13C n.m.r. spectroscopy which allows their specific identification.The ef
