The invention comprises a method for the oxidation of alkanes to alcohols and for decomposition of hydroperoxides to alcohols utilizing new compositions of matter, which are metal complexes of porphyrins. Preferred complexes have hydrogen, haloalkyl or haloaryl groups in meso positions, two of the opposed meso atoms or groups being hydrogen or haloaryl, and two of the opposed meso atoms or groups being hydrogen or haloalkyl, but not all four of the meso atoms or groups being hydrogen. Other preferred complexes are ones in which all four of the meso positions are substituted with haloalkyl groups and the beta positions are substituted with halogen atoms. A new method of synthesizing porphyrinogens is also disclosed.

Method for hydroperoxide decomposition using novel porphyrins

Alkanes are converted to unsaturated carboxylic acids by contacting an alkane with an oxidizing agent and a heteropolyacid or polyoxoanion comprising (1) at least 9 atoms of a first framework metal or metals comprising molybdenum, tungsten or vanadium or combinations thereof and (2) 1 to 3 atoms of a second framework metal or metals comprising zinc or a transition metal different from the first framework metal.

Conversion of alkanes to unsaturated carboxylic acids

The invention comprises a method for the catalytic conversion of alkanes and alkylhydroperoxides to oxygenates, particularly alcohols, comprising the oxidation of alkanes to yield alkylhydroperoxides, alcohols, other reaction products and unreacted alkane, and the decomposition of said alkylhydroperoxides to form alcohols and oxygen. Decomposition of the alkylhydroperoxide in the presence of unreacted alkane increases the yield of alcohol. The process further comprises drying of the reaction mixture comprising alkylhydroperoxide. Suitable catalysts for the process of the invention comprise metal containing catalysts, including metal organic ligand catalysts such as unsubstituted and substituted metal complexes of porphyrins, phthalocyanines and acetylacetonates.

Process for increased yields of oxygenated products in two-step

The invention provides novel catalyst compositions, useful in the oxidation of hydrocarbons with air or oxygen to form hydroxy-group containing compounds and in the decomposition of hydroperoxides to form hydroxy-group containing compounds. The catalysts comprise transition metal complexes of a porphyrin ring having 1 to 12 halogen substituents on the porphyrin ring, at least one of said halogens being in a meso position and/or the catalyst containing no aryl group in a meso position. The compositions are prepared by halogenating a transition metal complex of a porphyrin. In one embodiment, a complex of a porphyrin with a metal whose porphyrin complexes are not active for oxidation of hydrocarbons is halogenated, thereby to obtain a haloporphyrin complex of that metal, the metal is removed from the haloporphyrin complex to obtain the free base form of the haloporphyrin, and a metal such as iron whose porphyrin complexes are active for oxidation of hydrocarbons and for the decomposition of alkyl hydroperoxides is complexed with the free base to obtain an active catalyst for oxidation of hydrocarbons and decomposition of alkyl hydroperoxides.

Haloporphyrins and their preparation and use as catalysts

A hydroxyl-containing pyrrolic compound having a hydroxyl group or a hydroxyl-containing group in the 2-position, optionally substituted in the beta positions, is condensed in an acidified two immiscible phase solvent system to produce excellent yields of the corresponding porphyrin or metal porphyrin.
