Site-specific isotopic labeling of 1,4-diene systems

Methods for preparing isotopically modified 1,4-diene systems from non-isotopically modified 1,4-dienes involve selective oxidation of one or more bis-allylic position(s), or the preparation of isotopically modified 1,4-diene systems via trapping pi-allylic complexes with a source of deuterium or tritium. Such methods are useful for preparing isotopically modified polyunsaturated lipid including polyunsaturated fatty acids and polyunsaturated fatty acid derivatives.

METHOD FOR CHEMICAL CONVERSION OF SUGARS OR SUGAR ALCOHOLS TO GLYCOLS

Methods for chemically converting sugars or sugar alcohols into polyols/glycols, wherein the sugars or sugar alcohols are converted by means of hydrogenolysis in the presence of a catalyst comprising at least one metal and on a carbon support, wherein a nitrogen-doped carbon support is used as a catalyst support. The disclosure provides methods for chemically converting sugars or sugar alcohols into glycols which permits the preparation of glycols with higher selectivity and reduces the formation of lactic acid as a by-product.

Method for the Direct Synthesis of Cu-Containing Silicoaluminate Material with the AEI Zeolite Structure, and the Catalytic Applications Thereof

The main object of the present invention is to provide a new method for preparing the copper-containing silicoaluminate form of the AEI zeolite structure by means of a direct synthesis methodology. This new process involves combining a organometallic copper-complex with an additional organic molecule capable of directing the crystallisation of the silicoaluminate form of the AEI zeolite structure as organic structure-directing agents (OSDAs).
