  铃木-宫浦反应机理的实时质谱研究

  摘要：

  在依次添加各种反应组分的过程中，使用质谱对铃木-宫浦反应进行实时监控，表明这些溶液中存在动态平衡。取决于条件，硼酸可以被脱水，去质子化，羟基化（或烷氧基化）或氟化。存在的钯-膦物质包括Pd（0）（芳基碘迅速氧化添加到其中），Pd（II）芳基碘化物络合物，通过碘化物配体解离形成的阳离子Pd（II）物质和Pd（II ）双芳基配合物，最终通过还原消除将产物挤出。在催化条件下未观察到氟化或氢（烷-）氧基化的钯配合物。排除了几种重金属化组合作为反应性伙伴，但仍有几种可能性，

  Disclosed is a method for producing polyalcohols in the form of sugar alcohols from the group comprising sorbitol and mannitol and other optional C 2 to C 6 polyols. According to said method, a monosccharide, disaccharide, oligosaccharide, or polysaccharide containing at least one glucose unit and/or at least one fructose unit is continously reacted with hydrogen at an elevated temperature and at a great pressure in an aqueous phase in the presence of a hydrogenating catlyst based on ruthenium or ruthenium oxide so as to obtain the inventive polyalcohols.

• Improved capacitance of NiCo2O4/carbon composite resulted from carbon matrix with multilayered graphene

  The optimized electric and ionic conductivity of metal oxides with pseudo-capacitive properties can greatly improve their electrochemical performances and can effectively amplify their applications in super-capacitors. Carbon spheres with multilayered graphene formed in their matrix are prepared by annealing them with sodium metal and they are combined with NiCo2O4 spheres by a simple hydro-thermal treatment. Structures and electrochemical performances of resulted samples are examined with X-ray diffraction, Raman scattering spectra, X-ray photoelectron spectroscopy, infrared spectroscopy, electron microscopy, gas physisorption, cyclic voltammetry and electrochemical impedance spectra, respectively. The largest specific capacitance of resulted composites is measured about 920 F g(-1) at 1 A g(-1), which is about 3.7 times larger than that of pure carbon spheres and 2.8 times larger than that of pure NiCo2O4 spheres. The formation of multilayered graphene in the matrix of carbon spheres not only increases the high specific capacitance based on electric double layers, but also makes metal oxides combined with them display greatly increased pseudo-capacitance. The electric and ionic conductivity of resulted composites with various weight ratios of NiCo2O4 and carbon spheres are respectively investigated and their effects on their electrochemical performances are also discussed.
