IN343973: A process for the preparation of epoxides of cyclic and acyclic aryl olefins using recyclable organic promoters

The invention relates to epoxidation of alkenes viz., styrene, indene, 1,2-dihydronapthalene and chromenes using recyclable  organic promoter in the presence of an inorganic base and a metal salt as a catalyst with hydrogen peroxide as an oxidant to producB138e  alkene epoxides in high yield (95%) and selectivity (96%) in absence of any organic solvent. Recyclable organic promoter represented by the formula (1).
