标题:在二氧化硅负载的铜催化剂上通过脱氢和脱水反应转化二醇
摘要:在一系列铜-二氧化硅催化剂z Cusio 2(z = 1-25 Wt.%cu)上研究了含有伯羟基和仲羟基官能团的1,3-多元醇(1,3-丁二醇)的气相转化,并通过多种技术(例如bet表面积,Tpr,Xrd,N 2 O化学吸附和uv-Vis-Drs)进行了全面表征.z Cusio 2催化剂的物理化学性质取决于金属负载量是高于还是低于铜单层表面覆盖率(z = 13.5 Wt.%cu).检测到与二氧化硅载体表现出不同程度的相互作用的铜物质.在低z值下,Cu 0弥散度较高(d ~40%)是由于难于还原的纳米级cu种类(3 Nm)的主要贡献,但对于z> 13.5 Wt.%的d,由于形成了较大的三维cu团簇,D突然下降至3-8%由于铜-二氧化硅相互作用降低而在较低温度下降低的物种(30 Nm). 在z Cusio 2上作为催化剂,1,3-丁二醇仲oh官能团的脱氢作用优于伯oh,因此有价值的酮是主要的反

标题 :Synthesis of terminal alkenes from internal alkenes via olefin metathesis
发明人：SCHRODI YANN; PEDERSON RICHARD L; KAIDO HIROKI; TUPY MICHAEL J
权利人:ELEVANCE RENEWABLE SCIENCES
摘要:This disclosure relates generally to olefin metathesis, and more particularly relates to the synthesis of terminal alkenes from internal alkenes using a cross-metathesis reaction catalyzed by an olefin metathesis catalyst. According to one aspect, for example, a method is provided for synthesizing a terminal olefin, the method comprising contacting, in the presence of a ruthenium alkylidene metathesis catalyst, an olefinic substrate comprised of at least one internal olefin with a cross metathesis partner comprised of an alpha olefinic reactant, under reaction conditions effective to allow cross-metathesis to occur, wherein the reaction conditions include a reaction temperature of at least 35° C. The methods, compositions, reactions and reaction systems herein disclosed have utility in the fields of catalysis, organic synthesis, and industrial chemistry.

权利人:Monroe Mary Beth; PETRYK NATALIE M
摘要:A degradable polyurethane (PUr) having degradation rates useful for hemostatic dressings for controlling bleeding in traumatic wounds. Degradable PUrs may be synthesized from degradable monomers based on hydrolytically labile esters and oxidatively labile thioethers using rapid click-chemistry reactions. Monomers may include trimethylolpropane tris(3-mercaptopropionate) (TMPMP), dipentaerythritol hexakis(3-mercaptopropionate) (DPEHMP), dipentaerythritol hexakis(3-mercaptopropionate) (DPEHMP) or 2,2'-(ethylenedioxy) diethanethiol reacted with hydroxyethyl acrylate, 3-buten-1-ol, 3-methyl-3-buten-1-ol, or 3-buten-2-ol. Synthesis of these monomers is rapid and has no byproducts or toxic catalysts that require removal, enabling polyol synthesis and immediate use in further polymerization

标 题 :Synthesis of hybrid inorganic nanoparticle structures using peptides
发明人：SLOCIK JOSEPH M; NAIK RAJESH R
权利人:US AIR FORCE
摘要:Bimetallic hybrid nanostructures exhibit enhanced properties beyond a single composition nanoparticle, but present technical challenges for synthesis that includes the ability to process two or more materials while offering control over structural arrangement. Unlike conventional synthetic strategies, biological systems are excellent manufacturers of complex inorganic materials which possess maximal functionality, quality, and structures. Using a bio-mediated approach, Applicants have developed a synthetic method for the controlled synthesis of bimetallic nanostructures using multifunctional peptides.

摘要:A solid phase synthetic method for making substituted 1,5-benzodiazepine-2-one or 1,5-benzothiazepine-2-one. The method is useful for synthesis of large numbers of compounds through automated parallel synthesis or combinatorial library generation and is thus important to rapid discovery or new therapeutic agents containing the base structure of 1,5-benzodiazepine-2-one or 1,5-benzothiazepine-2-one.

标 题:Diversity-oriented synthesis of N,N,O-trisubstituted hydroxylamines from alcohols and amines by N—O bond formation
发明人：CRICH DAVID; HETTIKANKANAMALAGE ASIRI; HILL JARVIS
权利人:UNIV GEORGIA
摘要:In one aspect, the disclosure relates to a method for the direct synthesis of complex N,N,O-trisubstituted hydroxylamines by N—O bond formation. In another aspect, the method can successfully be employed using a wide variety of commercially available alcohols and secondary amines and enables the construction of large fragment-based libraries of trisubstituted hydroxylamines for drug discovery purposes. Also disclosed are N,N,O-trisubstituted hydroxylamines having low basicity, high stability at ambient temperatures, and an inherent lack of reactivity towards acetylating and sulfonylating enzymes that confer mutagenicity on less-substituted hydroxylamines.
