Synthesis of 1-Aryl-1H-pyrazolecarbonitriles and Related Derivatives

The synthesis of 1-aryl-5-cyano-1H-pyrazole-4-carboxylic acid, ethyl esters 1 is described.Subsequent chemistry led to relatively simple and unique pyrazole derivatives.Most important of these are 1-aryl-5-(aminocarbonyl)-1H-pyrazole-4-carboxylic acids 2,

Cyanopyrazole intermediates

5-Cyano-1-substituted-1H-pyrazole-4-carboxylic acids and esters useful as intermediates to the corresponding 4-carboxyamide derivatives having herbicidal and algicidal activity.
