标题 :Synthesis of ruthenium or osmium metathesis catalysts

摘要:The present invention relates to the synthesis of highly active ruthenium and osmium carbene metathesis catalyst in good yield from readily available starting materials. The catalysts that may be synthesized are of the general formula n wherein: n M is ruthenium or osmium; n X and X 1 are independently any anionic ligand; n L and L 1 are any neutral electron donor ligand; and, n R and R 1 are each hydrogen or one of the following substituent groups: C 2 -C 20 alkenyl, C 2 -C 20 alkynyl, C 1 -C 20 alkyl, aryl, C 1 -C 20 carboxylate, C 1 -C 20 alkoxy, C 2 -C 20 alkenyloxy, C 2 -C 20 alkynyloxy, aryloxy, C 2 -C 20 alkoxycarbonyl, C 1 -C 20 alkylthio, C 1 -C 20 alkylsulfonyl and C 1 -C 20 alkylsulfinyl. Optionally, the substituent group may be substituted with one or more groups selected from C 1 -C 5 alkyl, halogen, C 1 -C 5 alkoxy, and aryl. When the substitute aryl group is phenyl, it may be further substituted with one or more groups selected from a halogen, a C 1 -C 5 alkyl, or a C 1 -C 5 alkoxy. Specific synthetic protocols for vinyl alkylidene catalysts wherein R is hydrogen and R 1 is —CHCR 12 R 13 and non-vinyl alkylidene catalysts are also disclosed. In addition to the ease of synthesis (typically a one-step synthesis), the reactions generally may be run at or above room temperature and the resulting products usually may be used without extensive post synthesis purification.

标题:Enzyme-catalytic method for the direct stereoselective synthesis of gamma-(acyloxy) carboxylic acids

摘要:The present invention is a method for the stereoselective straightforward synthesis of gamma-acyloxy carboxylic acids of novel structure starting from racemic gamma-hydroxy carboxylic acid salts that are obtained by alkaline hydrolysis of the racemic gamma-lactones. The salt is acylated by enzyme catalysis in an organic solvent containing an acyl donor and an immobilised lipase, on stirring at room temperature (ca 20 °C) until reaching the conversion rate required. After that, the reaction mixture is acidified and extracted and the product treated with catalytic amount of para-toluenesulfonic acid in toluene during the time required for the relactonisation of the unreacted salt enantiomer. Thereafter, the target gamma-acyloxy carboxylic acid formed from one enantiomer of the starting compound and relactonised gamma-lactone formed from the other, unreacted enantiomer of the starting compound are isolated using a routine separation method, such as distillation, extraction with NaHCO3 water solution followed by acidification or column chromatography.

标题 :Synthesis of the Micro-Porous Silica Gel and Its Application to the Preparation of Catalysts for C2 Oxygenates Synthesis from Syngas

摘要:A synthesis of the micro-porous silica gel and its application to preparation of catalysts for C 2 oxygenates synthesis from syngas is invented. The small particles of silica gel which are, produced by sol gel process are heated in a basic solution, followed by drying and/or calcinations, and thus form micro-porous silica as catalyst support. The basic solution can be one or a mixed solution of hydroxides, carbonates, bicarbonates, formates and acetates of alkali metal and ammonium. The obtained micro-porous silica can be impregnated with the solutions of rhodium salt and other transition element salts (as promoter precursors), followed by drying and/or calcinations, thus forming a micro-porous silica supported rhodium based catalyst. The rhodium salt can be RhCl 3 or Rh(NO 3 ) 3 . The promoter precursors can be water-dissolvable transition metal salts, rare earth metals salts, alkali metal salts and alkali earth metal salts. The obtained catalysts show high activity and selectivity in the synthesis of C 2 -oxygenates by the hydrogenation of CO under mild process conditions.
