The photocatalytic potential of a derivative family of the Keplerate type nano-porous Mo-O based polyoxometalates with general formula [Mo72VIMo60VO372(L)30(H2O)72]n- (L = CH3COO-, SO42-) (denoted Mo132) has been evaluated by a prototype photocatalytic decoloration reaction of aqueous rhodamine B. The Mo132 anions are found to be photocatalytically active centers, however they are unstable and subjected to decomposition in the solution form. The introduction of organic counter cations such as tetrabutylammonium (n-Bu4N+) and dioctadecyldimethylammonium (DODA+) can endow significant stability to the giant anions during the catalytic process. TOC changes and GC/MS measurements were done to identify the degradation products. Among the derivatives, compound 2 composed of n-Bu4N+ and Mo132 (L = CH3COO-) has been found to be the most active one towards the photocatalytic decoloration of RhB solution. The analytical mechanism indicates that both OH radicals and 1O2 participate in the photo degradation process. This journal is
Selective alkene oxidation with H2O2 and a heterogenized Mn catalyst: Epoxidation and a new entry to vicinal cis-diols

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.

The UV irradiation of aliphatic alcohols gave α-glycols as the principal products.The values of the dl-α-glycol to meso-α-glycol ratios obtained in each example were analyzed.The stereochemical course of the formation of α-glycols, their conformations and configurations were established on basis of 1H NMR data.
