Patent number: 6602817Abstract: Functionalized amine derivatives are prepared by reacting an amine, a carbonyl derivative, and an organoboron compound under mild conditions. Organoboronic acids react with amines and alpha-hydroxy aldehydes to give anti-alpha-amino alcohols with very high diastereoselectivities (>99% de). When optically pure alpha-hydroxy aldehydes are used in this process, no racemization occurs and the products are obtained with very high enantioselectivities (>99% ee). The reaction also works with unprotected glyceraldehyde to give the corresponding amino diol derivatives, while unprotected carbohydrates give the corresponding amino polyols. The chiral amino alcohol products of this process or their derivatives, react further with metals or non-metals to give adducts that are effective catalysts for a variety of asymmetric reactions. Overall, the present invention relies on the facile synthesis of the chiral amino alcohol ligands for the rapid construction of combinatorial libraries of chiral catalysts.Type: GrantFiled: October 22, 1999Date of Patent: August 5, 2003Assignee: University of Southern CaliforniaInventor: Nicos A.

Publication number: 20020013221Abstract: Mono- and bimetallic transition metal carbides, nitrides and borides, and their oxygen containing analogs (e.g. oxycarbides) for use as water gas shift catalysts are described. In a preferred embodiment, the catalysts have the general formula of M1AM2BZCOD, wherein M1 is selected from the group consisting of Mo, W, and combinations thereof; M2 is selected from the group consisting of Fe, Ni, Cu, Co, and combinations thereof; Z is selected from the group consisting of carbon, nitrogen, boron, and combinations thereof; A is an integer; B is 0 or an integer greater than 0; C is an integer; 0 is oxygen; and D is 0 or an integer greater than 0. The catalysts exhibit good reactivity, stability, and sulfur tolerance, as compared to conventional water shift gas catalysts. These catalysts hold promise for use in conjunction with proton exchange membrane fuel cell powered systems.Type: ApplicationFiled: March 30, 2001Publication date: January 31, 2002Inventors: Levi T.

Publication number: 20020013222Abstract: Noble metal catalysts supported by the boron nitride (BN) to be used for oxidizing the volatile organic compound (VOC) are provided. The noble metal is selected from a group consisting of platinum (Pt), palladium (Pd), rhodium (Rh) and Ruthenium (Ru). The process for forming the catalyst includes steps of dissolving a noble metal complex compound in an organic solvent for forming a solution, mixing the solution with the boron nitride (BN) for forming a wetted boron nitride (BN) such that the noble metal complex compound is spread on a surface of the boron nitride (BN), and reducing the noble metal complex on the surface of the wetted boron nitride (BN) into the noble metal at a specific temperature by a gas.Type: ApplicationFiled: February 5, 2001Publication date: January 31, 2002Inventors: Min-Hon Rei, Chi-Sheng Wu, Zhi-An Lin, Jen-Wei Pan
