标题:负载型平面氧化铁纳米粒子的合成及其炔烃加氢的化学和立体选择性
摘要:大自然使用酶通过结合fe 2+和h +受体/供体催化活性位点来解离和转移h 2.仿生方法之后,据报道这里有很小的平面fe 2,3+氧化物纳米颗粒(2.0+/-0.5 Nm)负载在弱酸性无机氧化物(纳米晶tio 2,Zro 2,Zno)上作为双功能催化剂解离和转移h 2对炔烃有化学选择性和立体选择性.该催化剂通过在载体的等电点处将fe 0纳米颗粒氧化分散而合成.反应生成的fe 2 +,3 +固体不仅批量催化不同炔烃的半氢化反应,而且收率高,而且从乙烯流中去除乙炔的转化率和选择性均> 99.9%.这些高效,耐用的非贵金属催化剂是基于pd的现有工业技术的替代品,构成了朝着完全可持续且无毒的选择性加氢固体催化剂设计迈出的一步.

标题:Method of regioselective synthesis of substituted benzoates
发明人：KRAUS GEORGE A
权利人:KRAUS GEORGE A; UNIV IOWA STATE RES FOUND INC
摘要:A method of synthesis of para-substituted benzoate esters and acids is provided, wherein the para-substituted regioisomer is obtained substantially free of the meta-substituted impurity, the method comprising contacting a coumalate ester or acid and an unactivated alkene at elevated temperature in the presence of a metal oxidation catalyst and an oxidant. The metal oxidation catalyst can be palladium, such as palladium on carbon, and the oxidant can be the oxygen gas in ambient air. The reaction can be carried out without solvent or in high boiling hydrocarbon solvents such as mesitylene. When the unactivated alkene is a monosubstituted alkene, yields of at least about 50 or 60% of para-substituted ester and acid products, respectively, are obtained, substantially free of the regioisomeric meta-substituted impurity.

标 题:High activity ruthenium and osmium metal carbene complexes for olefin metathesis reactions
发明人：GRUBBS ROBERT H; NGUYEN SONBINH T; JOHNSON LYNDA K
权利人:CALIFORNIA INST OF TECHN
摘要:Disclosed are ruthenium and osmium carbene compounds which are stable in the presence of a variety of functional groups and which can be used to catalyze olefin metathesis reactions on strained and unstrained cyclic and acyclic olefins. Specifically, the present invention relates to carbene compounds of the formula ##STR1## wherein: M is Os or Ru; R and R 1 are independently selected from hydrogen and substituent groups C 2 -C 20 alkenyl, C 2 -C 20 alkynyl, C 1 -C 20 alkyl, aryl, C 1 -C 20 carboxylate, C 2 -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 or C 1 -C 20 alkylsulfinyl; each substituent group optionally substituted with C 1 -C 5 alkyl, a halogen, C 1 -C 5 alkoxy or with a phenyl group optionally substituted with a halogen, C 1 -C 5 alkyl or C 1 -C 5 alkoxy; X and X 1 are independently selected from any anionic ligand; and L and L 1 are each trialkyl phosphine ligands where at least one of the alkyl groups on the phosphine is a secondary alkyl or a cycloalkyl. A broad array of metathesis reactions are enabled including ring-opening metathesis polymerization of cyclic olefins, ring closing metathesis of acyclic dienes, cross metathesis involving at least one acyclic or unstrained cyclic olefin, depolymerization of unsaturated polymers and synthesis of telechelic polymers.

摘要:A method for the direct stereospecific conversion of structurally diverse mono-, di-, tri- and tetra-substituted olefins to N—H, N-alkyl, N-cycloalkyl, or N-aralkyl aziridines using a hydroxylamine amination agent with transition metal catalyst. The method is operationally simple (i.e., one-pot), scalable and fast at ambient temperature.
