1,3-Disulfonic Acid Imidazolium Trifluoroacetate as a Highly Efficient and Dual-Functional Catalyst for the Pseudo Five-Component Reaction of Phenylhydrazine with Ethyl Acetoacetate and Arylaldehydes
Ionic liquid 1,3-disulfonic acid imidazolium trifluoroacetate ([Dsim][TFA]) has been exploited as a highly efficient catalyst for the one-pot pseudo five-component reaction of phenylhydrazine (2 eq.) with ethyl acetoacetate (2 eq.) and arylaldehydes (1 eq.) in ethanol (reflux conditions). In this reaction, 4,4′‐(arylmethylene)‐bis(3‐methyl‐1‐phenyl‐1H‐ pyrazol‐5‐ol)s have been obtained in high ...
