Abstract

The solid state reaction of 3-methyl-1-phenyl-5-pyrazolon(eM PP) with aromatic aldehydes and ketones, benzil derivatives and imides, and the solid state Michael addition reaction of MPP with 4-arylidene-3-methyl-lphenyl-5-pyrazolone2 were investigated. Some new solid state reactions between the reactants were found, from which a series of new compounds were obtained. The structures of the products were identified by IR,1H NMR, MS, elemental analyses and also by X-ray crystal analysis, and the reaction mechanism of MPP with aromatic aldehydes and ketones was proposed.
