CHROMIUM-CATALYZED PRODUCTION OF ALCOHOLS FROM HYDROCARBONS IN THE PRESENCE OF OXYGEN

Processes for converting a hydrocarbon reactant into an alcohol compound and/or a carbonyl compound are disclosed in which the hydrocarbon reactant and either a supported chromium (VI) catalyst or a supported chromium (II) catalyst are contacted, optionally with UV-visible light irradiation, followed by exposure to an oxidizing atmosphere and then hydrolysis to form a reaction product containing the alcohol compound and/or the carbonyl compound. The presence of oxygen significant increases the amount of alcohol/carbonyl product formed, as well as the formation of oxygenated dimers and trimers of certain hydrocarbon reactants.

Oxidizing liquid media for chemical transformations

Provided is an oxidizing composition, in which a liquid medium is substantially inert in the presence of an oxidizing electrophile contained in the liquid medium. The composition comprises (a) an oxidizing electrophile comprising a main group element in oxidized form and at least one conjugate anion of an oxygen acid; (b) a non-oxidizable liquid selected from a fluorinated hydrocarbon, a sulfone, a deactivated arene, a deactivated aliphatic, a deactivated heteroarene, a deactivated heteroaliphatic, and a combination thereof; and (c) optionally one or more salt additives. Further provided are a method of using the oxidizing composition to oxidize a substrate and a method of generating and/or regenerating an oxidizing electrophile comprising a main group element.

Oxidation of alkane to alkene

Provided is a process for converting an alkane to an alkene. The process comprises (a) contacting the alkane and either (i) an oxidizing electrophile comprising a main group element in oxidized form, or (ii) an oxidant and a reduced form of the oxidizing electrophile, in a liquid medium comprising an oxygen acid and optionally one or more additives selected from a non-oxidizable liquid, a salt additive, a Lewis acid, and water, to provide an oxidized intermediate and a reduced form of the oxidizing electrophile; (b) optionally separating the oxidized intermediate and the reduced form of the oxidizing electrophile; and (c) performing an elimination reaction on the oxidized intermediate to provide the alkene and the oxygen acid.
