Synthesis of oxazolone and imidazolone derivatives in presence of H2O2 promoted fly ash as a novel and efficient catalyst

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.
