Patent number: 7025945Abstract: An anhydrous chloride with a formula of MCl2 (M=Fe, Co or Ni) is dissolved into an anhydrous acetonitrile solvent to form a chloride-acetonitrile solution. Then, calcium carbide minute powders are added and dispersed in the chloride-acetonitrile solution at a molar quantity equal to or smaller by 1–30 mol % than the molar quantity of the anhydrous chloride to form a reactive solution. Then, the reactive solution is heated at a predetermined temperature to chemically react the anhydrous chloride with the calcium carbide minute powders in the reactive solution to form a transition metal acetylide compound having an M-C2-M bond, a tetragonal structure, and a formula of MC2 (herein, M=Fe, Co or Ni).Type: GrantFiled: September 20, 2004Date of Patent: April 11, 2006Assignee: Inter-University Research Institute Corporation National Institutes of Natural SciencesInventors: Nobuyuki Nishi, Kentaro Kosugi

Patent number: 7019145Abstract: The invention concerns an improved method for preparing catalysts for hydrosilylation reactions of compounds with ethylene or acetylene unsaturation (for example olefins or acetylene derivatives), in particular but not exclusively those involving polyorganosiloxanes (POS) bearing Si—H units and POS bearing Si-(ethylene or acetylene unsaturation) units. Said preparation corresponds to the following synthesis (I), wherein: A=B=carbon: T1, T2=cyclohexyl, t-butyl or methyl; T3, T4=H; DVTMS=divinyltetramethylsiloxane; t-BuOK=potassium tert-butylate; T.A=room temperature. The invention is characterised in that it consists in carrying out said synthesis in a single step by bringing together salt (III) above, Karstedt (IV) in the presence of a solvent (V) (THF) and a base (VI) (t-BuOK) at room temperature.Type: GrantFiled: June 4, 2002Date of Patent: March 28, 2006Assignee: Rhodia ChimieInventors: Olivier Buisine, Istvan Marko, Sebastien Sterin

Patent number: 7019158Abstract: Chiral organometallic compounds are provided which comprise certain non-symmetrically substituted cyclopentadiene complexed to a transition metal. The cyclopentadiene has a second coordinating group which also complexes the transition metal and is attached to the cyclopentadiene by means of a chiral connecting chain. Preferred transition metals include rhodium, ruthenium, iridium, cobalt, iron, manganese, chromium, tungsten, molybdenum, nickel, palladium, or platinum. These chiral organometallic compounds find use in asymmetric synthesis to produce chiral compounds.Type: GrantFiled: August 2, 2002Date of Patent: March 28, 2006Assignee: Avecia LimitedInventor: Richard John Whitby
