标题:Process for the direct synthesis of trialkoxysilane
发明人：LEWIS KENRICK M; MEREIGH ABELLARD T; O'YOUNG CHI-LIN; CAMERON RUDOLPH A
权利人:MOMENTIVE PERFORMANCE MAT INC
摘要:The Direct Synthesis of trialkoxysilane is carried out by conducting the Direct Synthesis reaction of silicon and alcohol, optionally in solvent, in the presence of a catalytically effective amount of Direct Synthesis catalyst and an effective catalyst-promoting amount of Direct Synthesis catalyst promoter, said promoter being an organic or inorganic compound possessing at least one phosphorus-oxygen bond.

标题 :Direct synthesis of alkenylhalosilanes
发明人：LEWIS KENRICK MARTIN; ZHU YANJUN; BYRNE CHRISTOPHER M
权利人:MOMENTIVE PERFORMANCE MAT INC
摘要:A process for the direct synthesis of alkenylhalosilane monomers. Forming a slurry of liquid and copper-activated silicon from fresh silicon, cyclone fines and/or fine dust from silicon grinding, ultrafines and/or spent contact mass from the Direct Synthesis of alkylhalosilanes and arylhalosilanes, in a thermally stable solvent. Reacting the silanes by agitating the slurry with at least one unsaturated aliphatic or cycloaliphatic organohalide of the formula R1X, and optionally an organohalosilane and/or hydrogen halide, in the presence of a polymerization inhibiting Lewis base additive, at a reaction time, temperature and pressure effective to produce alkenylhalosilanes having the formulae, R1SiHX2, R12SiHX, R13SiX, R1SiX3, and R12SiX2 or mixtures thereof.

标 题:Synthesis of 2-aralkoxyadenosines and 2-alkoxyadenosines
发明人：MOORMAN ALLAN R
权利人:KING PHARMACEUTICALS RES & DEV
摘要:The invention provides new methods for synthesis of 2-aralkyloxyadenosines and 2-alkoxyadenosines. The invention is particularly useful for synthesis of 2-[2-(4-chlorophenyl)ethoxy]adenosine. Preferred methods of the invention include activating a guanosine compound followed by hydrolysis; alkylating the hydrolyzed compound with subsequent animation to provide a 2-aralkyloxyadenosine or a 2-alkoxyadenosine compound.

标题 :Nanosized copper catalyst precursors for the direct synthesis of trialkoxysilanes
发明人：LEWIS KENRICK M; ENG REGINA NELSON; CROMER SABRINA R; MEREIGH ABELLARD T; O'YOUNG CHI-LIN
权利人:MOMENTIVE PERFORMANCE MAT INC
摘要:The present invention provides a process for using nanosized copper, nanosized copper oxides, nanosized copper chlorides, other nanosized copper salts, and mixtures thereof, as sources of catalytic copper in the Direct Synthesis of trialkoxysilanes of the formula HSi(OR) 3 wherein R is an alkyl group containing from 1 to 6 carbon atoms inclusive. The nanosized copper, nanosized copper oxides, nanosized copper chlorides, other nanosized copper salts, and their mixtures of this invention have average particle sizes that are in the range from about 0.1 to about 600 nanometers, preferably from about 0.1 to about 500 nanometers, and most preferably from about 0.1 to about 100 nanometers. Nanosized sources of catalytic copper afford high dispersion of catalytic sites on silicon and contribute to high reaction rates, high selectivity and high silicon conversion. The nanosized copper catalyst precursors of the invention permit the use of substantially reduced levels of copper compared to conventional practice.

Nanosized sources of catalytic copper afford high dispersion of catalytic sites on silicon and contribute to high reaction rates, high selectivity and high silicon conversion. The nanosized copper catalyst precursors of the invention permit the use of substantially reduced levels of copper compared to conventional practice.
