  Mixed-ligand ternary complexes of potentially pentadentate but functionally tridentate Schiff base chelates

  摘要：

  The potentially pentadentate chelate 2,6-diacetylpyridine-bis(N-methyl-S-methyldithiocarbazate) (Nmedapsme) has been synthesized and structurally characterized by X-ray diffraction. Its reactions with nickel(II) salts did not lead to pentadentate coordinated ligand complexes but ternary complexes of general formula, INi(Nmedapsme)(nmesme)L]X center dot H2O (L = Br-, I- ; X =I-, BF4-) where Nmedapsme binds as a tridentate and nmesme = N-methyl-S-methyldithiocarbazate. The related ternary nickel(II) complexes of formula, Ni(Nmedapsme)(nmetsc)Br-2 has also been prepared and characterized. X-ray crystal structures of [Ni(Nmedapsme)(nmesme)I]I center dot H2O and INi(Nmedapsme)(nmestne)Br]BF4 center dot H2O revealed that, in these complexes, the Nmedapsme ligand acts as a tridentate NNN donor while the distal S-donors are not coordinated. The bidentate (NS) ligand, nmesme coordinates to the nickel(II) ion via the amino nitrogen and the thione sulfur atoms, the sixth coordination site is occupied by an anion. In both complexes, the nickel(II) ion adopts a distorted octahedral configuration. The complex [Cu(nmesme)(2)(ONO2)]NO3 was obtained from an unsuccessful attempt to complex copper(II) with Nmedapsme. Hydrolysis of the parent Schiff base Nmedapsme occurred during complexation. An X-ray crystallographic structure analysis shows that the complex, [Cu(nmesme)(2)(ONO2)]NO3 has an approximately square-pyramidal geometry with the two nmesme ligands coordinated to the copper(II) ion as NS bidentate chelating agents via the amino nitrogen and thione sulfur atoms and the fifth coordination position of copper(II) is occupied by a monodentate nitrate ligand.

  摘要：

  The thermal decompositions of Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II) complexes of saccharin were studied in static air atmosphere. All of the complexes contain four molecules of coordination water and two molecules of crystallization water. The water molecules were removed in a single stage, except from the Zn(II) complex, which exhibited two endothermic effects. The dehydration process was usually accompanied by a sharp colour change. The anhydrous complexes exhibited a phase transition and the decomposition or combustion of saccharin occurred in the second and subsequent stages. The final decomposition products were identified by XRPD as the respective metal oxides. The kinetic parameters, such as the order of reaction and energy of activation for the dehydration stage, were evaluated and the thermal stabilities of the complexes are discussed.

Through total spontaneous resolution, it was possible to obtain optically active bulk products starting from achiral precursors only. It was discovered that crystallisation of two of the complexes was influenced by undetectable

  Allylic oxidation of hydrocarbon substrates is the foundation of many industrial and fine-chemical production processes. Direct allylic oxidation of cycloalkenes (C5-8) has been widely discussed in the chemical literature. However, certain mechanistic details related to the presence of allylic free radicals have yet to be fully resolved. The corresponding copper-catalyzed allylic amination reaction

  碳氢化合物底物的烯丙基氧化是许多工业和精细化学生产工艺的基础。环烯烃（C的直接烯丙基氧化5 - 8）已经在化学文献中被广泛讨论。但是，与烯丙基自由基的存在有关的某些机理细节尚未完全解决。先前尚未实现相应的铜催化的烯丙基胺化反应。我们报道了使用糖精和双-对甲苯磺酰胺作为氮源以及t-BuOOH和PhI（糖精）2进行此类胺化反应的第一个实例。作为氧化剂。对化学计量模型反应的动力学研究表明，氧化剂不参与转化的RDS，对3,3,6,6-四氘代环己烯的研究最终显示出催化氧化和胺化反应之间的机理二分法。二者的氧化过程涉及η 1 -烯丙基中间体，和区域化学的结果是离散的铜配合物的结果。涉及烯丙基转座的机理原理解释了这种机理的二分法。
