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 H2O2 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.

Linear-sweep voltammetry was used for determination of values KdCO = and KdCO = +R'>+)R'> for some aliphatic and alicyclic 1,2-diketones.Values obtained were compared with data obtained from UV and NMR spectra.Dc polarographic data were used to choose the most reliable value.In all cases, the protonated form predominating in solutions of sulfuric acid is less strongly hydrated than the unprotonated form.The effect of ring size on the hydration in polycyclic species is discussed.Steric hindrance of the hydration due to the 7- and possibly the 1-methyl group in 2,3-camphorquinone has been confirmed.
