发明人：ROMERO PATRICIO EDUARDO; VERVUURT RENÉ HENRICUS JOZEF; DEZELAH CHARLES; PORE VILJAMI J
权利人:ASM IP HOLDING BV
摘要:Disclosed are methods and systems for forming a silicon-containing layer on a substrate. Further disclosed are composition and synthesis of silicon-containing precursor. The methods for forming a silicon-containing layer comprise executing a plurality of deposition cycles. A deposition cycle comprises a first precursor pulse that comprises exposing the substrate to a first precursor. The first precursor comprises a molecule comprising a P—Si bond. A deposition cycle further comprises a plasma pulse that comprises exposing the substrate to a plasma treatment. The plasma treatment comprises generating a plasma.

摘要:A process for the production of ezetimibe and intermediates used in said process are disclosed. A kind of Morita-Baylis-Hillman adduct can be altered to chiral carboxylic acid derivatives of β-arylamino α-methylene with high activity and selectivity by means of ally lamination reaction, and the above carboxylic acid derivatives of β-arylamino α-methylene can be altered to the chiral intermediates of ezetimibe by means of simple conversion and further synthesized into the chiral drug ezetimibe. The synthesis route introduces chirality through the use of a chiral catalysis method, thereby avoiding the use of the chiral auxiliary oxazolidinone; and the route is economical and eco-friendly.

标题 :Method for the synthesis of pheromones
发明人：QUEVAL PIERRE; CAIJO FRÉDÉRIC; ROUEN MATHIEU; TRIPOTEAU FABIEN
权利人:DEMETA
摘要:The present invention relates to a method for synthesising pheromones and pheromone precursors, by means of the metathesis of terminal olefins including one functionalised olefin. The reaction is carried out in the presence of at least one particular catalyst, selected from among complexes of alkylidene ruthenium comprising a 1-aryl-3-cycloalkyl-imidazoline-2-ylidene ligand and mixtures thereof. The method can include an additional step of reducing the unsaturated compound formed.

摘要:The present disclosure is related to the development of improved fertilizer for precision and sustainable agriculture. A method was developed wherein efficient NPK nanocomposite for plant nutrition was synthesized in a single step using aerosol science and technology concepts. Further a formulation was prepared by addition of ZnO, TiO 2 and other nanoparticles to the NPK nanocomposite. Also, an aerosol based foliar application technique was developed for the precise delivery of nanoparticles to the plants.

摘要:The present invention relates to novel Ruthenium catalysts and related borohydride complexes, and the use of such catalysts, inter alia, for (1) hydrogenation of amides (including polyamides) to alcohols and amines; (2) preparing amides from alcohols with amines (including the preparation of polyamides (e.g., polypeptides) by reacting dialcohols and diamines and/or by polymerization of amino alcohols); (3) hydrogenation of esters to alcohols (including hydrogenation of cyclic esters (lactones) or cyclic di-esters (di-lactones) or polyesters); (4) hydrogenation of organic carbonates (including polycarbonates) to alcohols and hydrogenation of carbamates (including polycarbamates) or urea derivatives to alcohols and amines; (5) dehydrogenative coupling of alcohols to esters; (6) hydrogenation of secondary alcohols to ketones; (7) amidation of esters (i.e., synthesis of amides from esters and amines); (8) acylation of alcohols using esters; (9) coupling of alcohols with water to form carboxylic acids; and (10) dehydrogenation of beta-amino alcohols to form pyrazines. The present invention further relates to the novel uses of certain pyridine Ruthenium catalysts.
