Preparation of 4,4′-(arylmethylene)-bis(3-methyl-1-phenyl-1H-pyrazol-5-ol)s over 1,3-disulfonic acid imidazolium tetrachloroaluminate as a novel catalyst
RSC Advances Vol. 2, No. 21, 8010–8010
چکیده
In this work, a green, simple and efficient method for the synthesis of 4,4′-(arylmethylene)-bis(3-methyl-1-phenyl-1H-pyrazol-5-ol)s by the condensation of 1-phenyl-3-methylpyrazol-5-one with aromatic aldehydes using 1,3-disulfonic acid imidazolium tetrachloroaluminate {[Dsim]AlCl4} as a new, heterogeneous and reusable catalyst is reported.
