Abstract

Microwave-promoted rapid oxidation of toxic natural cis-phenylpropenes (1a–1e) into high valued methoxylated benzaldehydes (2a–2e) was achieved within 2 min in high yield (71– 84%) by reacting with sodium metaperiodate in the presence of catalytic amount of osmium tetraoxide (co-oxidant) and benzyltriethylammonium chloride (PTC).
