Abstract :
A new catalyst was prepared by promoting fly ash with hydrogen peroxide. The
catalytic activity of H2O2 promoted fly ash (HPFA) was evaluated by synthesis 5(4H)-
oxazolone and imidazolone derivatives under solvent free conditions. The possible
mechanisms of synthesis reactions were also suggested. These proposed methods
benefit in terms of low-cost catalyst, high yields, ease of workup, survival of different
functional groups, reusability of the catalyst and short reaction time. These advantages
render HPFA to be a promising catalyst for synthesis of organic materials.
