A versatile cobalt(II)-Schiff base catalyzed oxidation of organic substrates with dioxygen: Scope and mechanism

Cobalt(II) complex 1a-f derived from Schiff bases act as efficient catalysts during the oxidation of wide range of organic substrates(e.g. alkenes, alcohols, benzylic compounds and aliphatic hydrocarbons) with dioxygen in the presence of aliphatic aldehydes or ketones or ketoesters. EPR studies on 1a-f complexes suggest that the aliphatic carbonyl compounds promote the formation of a cobalt(II)-superoxo species responsible for the oxidation of organic compounds. These studies also demonstrate the role of ligands on cobalt in controlling the chemoselectivity of these oxidations. A plausible mechanistic rational is also provided for these oxidations.

"kick-Starting" oxetane photopolymerizations

In the presence of small amounts of 2,2-dialkyl-, 2,2,3-trialkyl-, or 2,2,3,3-tetraalkyl substituted epoxides such as isobutylene oxide, 1,2-limonene oxide, and 2,2,3,3,-tetramethyl oxirane, the photoinitiated cationic ring-opening polymerizations of 3,3-disubstituted oxetanes are dramatically accelerated. The acceleration affect was attributed to an increase in the rate of the initiation step of these latter monomers. Both mono- and disubstituted oxetane monomers are similarly accelerated by the above-mentioned epoxides to give crosslinked network polymers. The potential for the use of such "kick-started" systems in applications such as coatings, adhesives, printing inks, dental composites and in three-dimensional imaging is discussed.

Catalytic epoxidation of camphene using methyltrioxorhenium(VII) as catalyst

This work presents the epoxidation of camphene employing methyltrioxorhenium(VII) (MTO) as catalyst. The effect of different factors on the formation of camphene oxide with respect to high yield and selectivity was investigated. First, the ratio camphene:MTO:pyrazole:H2O2 was studied in dichloromethane as solvent in order to determine the optimal condition. Moreover, the influence of the Lewis base adduct (tert-butylpyridine, 4,4′-dimethyl-2,2′-bypridine, imidazole or pyrazole) was investigated. The effect of an aqueous oxidant, namely H2O 2 and a solid oxidant, namely urea hydrogen peroxide (UHP) was also examined. Finally, the solvent was varied from dichloromethane to chloroform, toluene and nitromethane. Based on the results the optimal conditions for the epoxidation of camphene using MTO as catalyst were determined. The molar ratio camphene:MTO:pyrazole:H2O2 of 100:0.5:10:110 in dichloromethane at room temperature leads after 3 h to 97% yield and 98% selectivity toward camphene oxide at 99% conversion.

Organocatalyzed epoxidation of alkenes in continuous flow using a multi-jet oscillating disk reactor

The times are changing: A batch process, the Minisci epoxidation, is transformed into a continuous-flow protocol for the selective aerobic radical epoxidation of alkenes. The use of a novel reactor type allows to considerably shorten reactor residence times. Experimental results suggest that two different reaction mechanisms exist for the oxidation: one for the batch conditions and a different one for flow synthesis protocol. Copyright

METHOD FOR MANUFACTURING AN EPOXY COMPOUND AND METHOD FOR EPOXIDIZING A CARBON-CARBON DOUBLE BOND

The present invention provides a method for producing an epoxy compound, comprising oxidizing a carbon-carbon double bond of an organic compound by hydrogen peroxide in the presence of a neutral inorganic salt and a mixed catalyst of a tungsten compound (a), at least one phosphorus compound selected from the group consisting of phosphoric acids, phosphonic acids, and salts thereof (b) and a surfactant (c), and an epoxidizing method comprising oxidizing a carbon-carbon double bond by hydrogen peroxide in the presence of the catalyst and the neutral inorganic salt.

Manganese (III) meso-tetrakis(p-sulfonatophenyl)-β-octabromoporphyrin (supported on Amberlite IRA-400 [Mn(Br8TPPS)-Ad-400] is a robust and efficient catalyst for epoxidation of alkenes and hydroxylation of alkanes with sodium periodate at room temperature.

Manganese(III) porphyrin supported on polystyrene as a heterogeneous alkene epoxidation and alkane hydroxylation catalyst

Carboxymethylated crosslinked polystyrene resin [poly(4-styrylmethylacylchloride) (PSA)] support have been used to covalently attach manganese(III) tetrakis(4-aminophenyl)-porphyrin. This catalyst was found to be efficient for alkene epoxidation and alkane hydroxylation by sodium periodate. This new hydrogenised catalyst is of high stability and reusability.

NaY zeolite as host for the selective heterogeneous oxidation of silanes and olefins with hydrogen peroxide catalyzed by methyltrioxorhenium

The methyltrioxorhenium(MTO)-catalyzed oxidation of silanes to silanols and the epoxidation of various olefins by aqueous 85% H2O2 proceed in high yields and excellent product selectivities (no disiloxanes, diols) in the presence of the zeolite NaY. The oxidative species is located inside the 12- A supercages. This prevents the bimolecular condensation of the silanol to disiloxane by steric means and the Lewis-acid assisted hydrolysis of the epoxide to the diol.
