专利号:US-7253324-B1 优先权日:2007-01-23 标 题:Process for the synthesis of biologically active oxygenated compounds by dealkylation of the corresponding alkylethers 发明人:MAJEED MUHAMMED; THOMAS SAMUEL MANOHARAN; NAGABHUSHANAM KALYANAM; BALAKRISHNAN SIVAPRAKASH KURUM; PRAKASH SUBBALAKSHMI 权利人:SAMI LABS LTD 摘要:Alkoxy aromatic compounds are conveniently dealkylated to the corresponding phenolic compounds by treatment with aluminum chloride/N,N-dimethyl aniline complex. Aromatic poly O-demethylation is a unique feature of this invention. This process is applicable to the manufacture of polyphenols such as Resveratrol, Oxyresveratrol, Gnetol.
专利号:US-6448412-B1 优先权日:1995-07-31 标题:Methods for the preparation and characterization of multi-substituted fullerenes 发明人:MURPHY RANDALL B; WILSON STEPHEN R; LU QUING 权利人:SPHERE BIOSYSTEMS INC 摘要:The invention is directed to multiply-substituted fullerene derivatives of novel configurations, and methods for their preparation and use. The methods involve the combinatorial synthesis of a library of fullerene derivatives and comprises the steps of forming a mixture of fullerene derivatives by reacting the C n fullerene with two or more reactive precursor compounds, and removing the unreacted compounds to yield the fullerene derivatives having the desired activity. Methods for the identification and screening of a combinatorial library of fullerenes by 3 He-nuclear magnetic resonance and electrospray mass spectrometry to define members with the optimal desired activity are also provided.
专利号:US-8927776-B2 优先权日:2010-11-08 标题 :Method for hydroformylation of unsaturated compounds 发明人:FRANKE ROBERT; BELLER MATTHIAS; JACKSTELL RALF; JENNERJAHN REIKO; PIRAS IRENE 权利人:FRANKE ROBERT; BELLER MATTHIAS; JACKSTELL RALF; JENNERJAHN REIKO; PIRAS IRENE; EVONIK DEGUSSA GMBH 摘要:The invention relates to a method for hydroformylation of unsaturated compounds such as olefins and alkynes using mixtures of synthesis gas (CO/H 2 ), in which either the unsaturated compounds and a catalyst are heated to a reaction temperature of 60 to 200° C. and the synthesis gas is then added, or the unsaturated compounds and the catalyst are brought into contact with pure CO at normal temperature in a preformation step, then are heated to reaction temperature and on reaching the reaction temperature the CO is replaced by the synthesis gas. The pressure is 1 to 200 bar and the CO:H 2 ratio in the synthesis gas is in the range from 1:1 to 50:1. The iridium catalyst used comprises a phosphorus-containing ligand in the iridium:ligand ratio in the range from 1:1 to 1:100. With high catalyst activities and low catalyst use, very high turnover frequencies are achieved.
