标 题:Ruthenium complexes and their uses as catalysts in processes for formation and/or hydrogenation of esters, amides and related reactions
发明人：MILSTEIN DAVID; HU PENG; FOGLER ERAN; RAO JAI ANAND GARG NARAYANA
权利人:YEDA RES & DEV
摘要:The present invention relates to novel Ruthenium complexes of formulae A1-A4 and their use, inter alia, for (1) dehydrogenative coupling of alcohols to esters; (2) hydrogenation of esters to alcohols (including hydrogenation of cyclic esters (lactones) or cyclic di-esters (di-lactones), or polyesters); (3) preparing amides from alcohols and amines—(including the preparation of polyamides (e.g., polypeptides) by reacting dialcohols and diamines and/or polymerization of amino alcohols and/or forming cyclic dipeptides from p-aminoalcohols; (4) hydrogenation of amides (including cyclic dipeptides, polypeptides and polyamides) to alcohols and amines; (5) hydrogenation of organic carbonates (including polycarbonates) to alcohols or hydrogenation of carbamates (including polycarbamates) or urea derivatives to alcohols and amines; (6) dehydrogenation of secondary alcohols to ketones; (7) amidation of esters (i.e., synthesis of amides from esters and amines); (8) acylation of alcohols using esters; (9) coupling of alcohols with water and a base to form carboxylic acids; and (10) preparation of amino acids or their salts by coupling of amino alcohols with water and a base. The present, invention further relates to the use of certain known Ruthenium complexes for the preparation of amino acids or their salts from amino alcohols.

标 题:On-slide synthesis of a schiff reagent
发明人：BIRD JEAN MARIE; CANTORIA MARY JO CASTRO; DURRANT EDWARD E; HANNON ANDREW
权利人:VENTANA MED SYST INC
摘要:The present disclosure is directed to compositions, kits, and methods for synthesizing a Schiff's reagent in situ, i.e., directly on a substrate, such as within a puddle disposed on the surface of a substrate. In some embodiments, the kits comprise at least a dye composition and a sulfite composition. In some embodiments, the dye composition comprises a compound having a 4-Benzhydrylidene-2,5-cyclohexadien-1-imine core functionalized to include at least two substituted or unsubstituted amine groups, wherein the compound has a molecular weight ranging from between about 300 g/mol to about 600 g/mol. In some embodiments, the dye composition optionally includes an acid. In some embodiments, the sulfite composition comprises a sulfite or SO2 source.

标 题 :Preparation of rhodium and iridium hydride carbonyl complexes
发明人：BOOTH FRANK B; FENTON DONALD M; OLIVIER KENNETH L
权利人:UNION OIL CO
摘要:HYDRIDE CARBONYL COMPLEXES OF RHODIUM AND IRIDIUM WITH BIPHYLIC LIGANDS ARE PREPARED BY TREATMENT OF RHODIUM OR IRIDIUM, COMPLEXES OR SALTS THEREOF WITH AN ALKALI METAL HYDROXIDE, ALKOXIDE OR ARYLOXIDE AND A BIPHYLLIC LIGAND AND A MIDL REDUCING AGENT. IN A TYPICAL SYNTHESIS A RHODIUM CARBONYL SALT IS CONTACTED WITH AN ALKALI METAL ALKOXIDE IN THE PRESENCE OF THE LIGAND AND THE HYDRIDE IS FORMED BY SUBSEQUENT OR SIMULTANEOUS CONTACTING WITH A REDUCING AGENT SUCH AS HYDROGEN, CARBON MONOXIDE OR AN OXIDIZABLE ALCOHOL. THE COMPOUNDS HAVE UTILITY AS HYDROFORMYLATION CATALYSTS.
