AN ECO-FRIENDLY ONE-POT SYNTHESIS OF 4,4'-(ARYLMETHYLENE)BIS(1H-PYRAZOL-5-OLS) USING [Et3NH][HSO4] AS A RECYCLABLE CATALYST
A simple and efficient procedure for synthesis of 4,4'-(arylmethylene)bis(1H-pyrazol-5-ols) by one-pot three-component condensation of aromatic aldehydes, ethyl acetoacetate, and phenylhydrazine/hydrazine hydrate under solvent-free conditions in the presence of [Et3NH][HSO4] as catalyst is desc...
