Abstract

In this work, a green, simple and efficient method for the synthesis of 4,49-(arylmethylene)-bis(3-methyl-1-phenyl-1Hpyrazol-5-ol)s by the condensation of 1-phenyl-3-methylpyrazol-5-one with aromatic aldehydes using 1,3-disulfonic acid imidazolium tetrachloroaluminate {[Dsim]AlCl }asa new, heterogeneous and reusable catalyst is reported. 4
