摘要:由叔-β-二氯乙胺(1)与α-S-酰胺锂反应制得1,2-双二烷基氨基乙烯(亚乙烯基胺)(3).结果表明,在反应条件下(3)的形成取决于1,1,2-三二烷基氨基链烷中间体(2)的存在.这又取决于碳负离子的先前形成,如果(1)中的β-氢被烷基取代,该碳负离子将不存在.相反,起始β-二氯烷基胺(7)被还原为一氯衍生物.2-(1,1-二氯丙基)二乙胺(9)通过与二乙酰胺锂反应生成1,1-双二乙氨基丙烯(10).讨论了所涉及的重排.

标题:Process for the selective synthesis of ethylene diamines
发明人：MARSELLA JOHN A
权利人:AIR PROD & CHEM
摘要:The present invention is a process for the selective synthesis of alkanediamines by reacting a secondary amine with an alkanediol. High conversions and high selectivity for the production of alkanediamines is achieved by carrying out the reaction in the presence of a compound or complex of ruthenium in the absence of an organic phosphine co-catalyst.

摘要:The synthesis of certain polyester diols (PEDs) is disclosed. This application also discloses the purification and polymerization kinetics of lipid based PEDs. Molecular weight and distribution controls were achieved by initial and induced stoichiometric imbalance and optimization of the purification protocol. Thermal degradation and thermal transition behavior of the PEDs were also investigated by TGA and DSC.

摘要:The present invention belongs to the field of chemistry and chemical engineering, and disclosed are a type of Si-O-Si framework bridged multi-nuclear boron catalyst, a preparation method therefor, and a use thereof. The Si-O-Si framework of the Si-O-Si framework bridged multi-nuclear boron catalyst can be a linear structure of Si-O-Si, a ring structure of Si-O-Si, or a cage structure of Si-O-Si. The feasibility of multiple types of topological structures provides controllability for the synthesis of multi-nuclear boron. The multiple Lewis acid centers of this type of system can better activate monomers and stabilize active species, reflecting the synergistic effect of multiple boron centers. The multi-nuclear boron catalyst of the present invention is mainly used in ring-opening polymerization and copolymerization to prepare diverse low-carbon polymers, such as polyethers, polyesters, polycarbonates, etc.

标题:Process for synthesis of allophanate compounds and compositions including the product thereof
发明人：TAZZIA CHARLES L
权利人:BASF CORP
摘要:The invention provides a process for preparing an allophanate-containing compound in the presence of a metal catalyst and a tertiary amine. In a preferred process, the tertiary amine compound also has a hydroxyl group. The hydroxyl group can react with the isocyanate functionality. Also disclosed is a process in which an allophanate-containing compound is prepared with copper acetate monohydrate as a catalyst. The allophanate-containing compound is used as a curing agent in coating compositions, particularly electrocoat coating compositions. The coating compositions are used to coat articles.

标 题 :Selective synthesis of substituted amines
发明人：MARSELLA JOHN A
权利人:AIR PROD & CHEM
摘要:Selective mono- or di-amination of alkanediols is controllably obtained by catalytic reaction with secondary amines at moderate temperature and autogenous pressure, by selection of the catalyst employed. Ruthenium complexes compounded or admixed with selected organic phosphines, such as triphenylphosphine, favor high yields of alkanolamines, while ruthenium complexes in the absence of organic phosphines favor production of alkylenediamines. Iridium complexes with or without organic phosphines in admixture or chemical combination, also promote production of alkylenediamines.
