Abstract

Abstract : The Mn x O y oxide derivatives, mainly Mn3 O4 nanoaggregates, were generated in situ by KMnO4 /H2 O2 during the synthesis of vicinal cis -diols from olefins. Abstract : A novel protocol for the practical and green synthesis of vicinal cis -diols from 10.0 mmol olefins by using 5.0 mmol KMnO4 as oxidant and 30.0 mmol H2 O2 as co-oxidant is reported. The presented procedure is easy to carry out and enables the direct transformation of linear and cyclic alkenes to the corresponding vicinal cis -diols. The synthesis of vicinal cis -diols by dihydroxylation of olefins with a KMnO4 /H2 O2 system was catalyzed by in situ generated Mn x O y nanoaggregates. The use of H2 O2 as a co-oxidant is the key for the protocol to synthesize vicinal cis -diols in high yields, because it assists the oxidation of Mn x O y nanoaggregates, which have an active role in the oxidation reaction medium.
