Abstract

Abstract Covalent anchoring of 1, 4-dimethyl-1, 4, 7-triazacyclononane on silica gel is the first step in the preparation of a heterogenized Mn catalyst. When H 2 O 2 is used as the oxidant, this material can catalyze the vicinal cis-dihydroxylation of disubstituted olefins, as shown schematically here. Both enantiomers of the product are obtained.
