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 quantum dots

摘要:Common approaches to synthesizing alloyed quantum dots employ high-cost, air-sensitive phosphine complexes as the selenium precursor. Disclosed quantum dot synthesis embodiments avoid these hazardous and air-sensitive selenium precursors. Certain embodiments utilize a combination comprising a thiol and an amine that together reduce and complex the elemental selenium to form a highly reactive selenium precursor at room temperature. The same combination of thiol and amine acts as the reaction solvent, stabilizing ligand, and sulfur source in the synthesis of quantum dot cores. A non-injection approach may also be used. The optical properties of the quantum dots synthesized by this new approach can be finely tuned for a variety of applications by controlling size and/or composition of size and composition. Further, using the same approach, a shell can be grown around a quantum dot core that improves stability, luminescence efficiency, and may reduce toxicity.

摘要:In this method, an oligonucleotide represented by formula (II) [wherein Y 1 , Q, Base, r and r′ are each as defined in claim 1 ] is prepared by using, as a synthesis unit, a novel nucleoside monomer compound represented by formula (I) [wherein X, R 1 , Y, Base, Z, Ar, R 2 , R 3 and n are each as defined in claim 1 ]. The novel nucleoside monomer compound is a nucleoside, the base moiety of which is substituted with an aromatic-hydrocarbon-ring-carbonyl or -thiocarbonyl group having at least one hydrophobic group. The method can dispense with column-chromatographic purification in every reaction, and enables base elongation not only in the 3′-direction but also in the 5′-direction, thus attaining efficient liquid-phase mass synthesis of an oligonucleotide.

摘要:A method of making a compound of Formula I′ n ncomprises reacting a compound of the formula DLCHO, with a compound of the formulan n nto produce the compound of Formula I′. Methods of using the compounds are also described, particularly as intermediates for the synthesis of porphyrin rods, which porphyrin rods are in turn useful for (among other things) the production of molecular memory devices.

标 题:Synthesis of cannabinoids and cannabinoid precursors, and related compounds, formulations, and methods of use
发明人：SAMMIS GLENN M; ROGGEN MARKUS
权利人:NALU BIO INC
摘要:Methods are provided for the synthesis of cannabinoids, including cannabidiol (CBD), cannabinol (CBN), cannabichromene (CBC), cannabidiolic acid (CBDA), cannabigerol (CBG), cannabigerolic acid (CBGA), cannabidivarin (CBDV), cannabidibutol (CBD-C4), dihydrocannabidiol (DCBD), tetrahydrocannabivarin (THCV), analogs thereof, and precursors to the foregoing. One method employs phloroglucinol or a phloroglucinol analog as a starting material. The syntheses are stereospecific, efficient, selective, and cost-effective, with little or no potential for generation of THC ((−)-trans-Δ9-tetrahydro-cannabinol) or any other psychoactive side product. Telescoped syntheses are also provided, as are new cannabinoids, pharmaceutical formulations, and methods of use.

标 题 :Process for the synthesis of nanocrystalline phosphor particles and nanocrystalline phosphor particles obtainable by this process
发明人：FELDMANN CLAUS; BUEHLER GUNNAR

摘要:The present invention relates to a process for the targeted synthesis of inorganic phosphor particles which have a particle diameter from 1 to 100 nm, a virtually monodisperse size distribution in the range of ±20% and, depending on the class of material selected, a quantum yield of at least 20%, inorganic phosphor particles obtainable by this process and also their use for coating or embedding in a substrate selected from the group consisting of a paper, polymer, glass, metal or ceramic substrate, for example for diagnostics, therapy, as contrast agent, as marking, safety feature, for illumination and for data storage and/or data reproduction. A particular advantage of the phosphor particles which can be obtained according to the invention is, inter alia, that the particles have a surface finish which allows agglomerate-free redispersion in polar and nonpolar solvents or dispersion media. The choice of the dispersion medium allows the physicochemical properties of the phosphor particles which can be obtained according to the invention to be specifically matched to the requirements of a particular application.
