This invention is directed to a method of oxidation of 5-chloro-2-((3,4,4-trifluorobut-3-en-1-yl)thio)-1λ,3λ-thiazole and analogs thereof to the corresponding sulfone, using an oxidant and a metal oxide-based catalyst.

Process for the preparation of fluensulfone

This invention is directed to a method of oxygenating hydrocarbons with molecular oxygen, O, as oxidant under electrochemical reducing conditions, using polyoxometalate compounds containing copper such as Q[Cu(HO)(B-α-PWO)] or Q{[Cu(HO)][(A-α-PWO)(NO)]} or solvates thereof as catalysts, wherein Q are each independently selected from alkali metal cations, alkaline earth metal cations, transition metal cations, NH, Hor any combination thereof.

Aerobic electrocatalytic oxidation of hydrocarbons

This invention relates to electrocatalytic processes for the formation of formate esters using at least one catalyst or pre-catalyst; wherein the formate ester can be further hydrolyzed.

Electrochemical mono-hydroxylation of organic compounds

This invention is directed to a method of oxygenating hydrocarbons with molecular oxygen, O, as oxidant under electrochemical reducing conditions, using polyoxometalate compounds based on the so-called Keplerate capsules, such as [{(W)WO(SO)}{(Fe(HO))}(SO)(HO)]or [{(Mo)MoO)(X')}{Fe(HO)(X)}] or solvates thereof as catalysts, wherein X&#x2032;and Xare each independently selected from HO, MoO, MoO, CHCOO(acetate), or any combination thereof.

Electrochemical oxygenation of hydrocarbons

The invention relates to electrocatalytic processes for the formation of formate esters using at least one catalyst or pre-catalyst; wherein the formate ester can be further hydrolyzed.

The present invention relates to methods of preparing carbon monoxide (CO) and hydrogen (H) by reacting biomass, a biomass component (e.g., lignin, ligno-cellulose, cellulose, hemiceullose or combination thereof) or a carbohydrate from any source with a polyoxometalate catalyst such as HPVMoO, or solvates thereof, in the presence of a concentrated acid, under conditions sufficient to yield carbon monoxide (CO); followed by electrochemical release of hydrogen (H). The carbon monoxide (CO) and hydrogen (H) may be combined in any desired proportion to yield synthesis gas (Syngas). The present invention further relates to methods for preparing H, CO and formic acid/formaldehyde from biomass, a biomass component and/or from carbohydrates.
