  溶剂依赖性阴离子解离限制了铜（i）催化的原子转移反应

  摘要：

  原子转移自由基加成反应（ATRA）和聚合反应（ATRP）通常由铜（Ⅰ）配合物催化，它们与休眠的烷基卤化物引发剂（RX）可逆地反应，释放出反应性有机基团R 4。铜催化剂承载一个多齿N-供体配体（L）和活性催化剂仅仅是铜我L.催化剂在这些反应中的作用是从RX形成相应较高氧化态物种的Cu抽象卤原子II LX。然而，为了执行其催化功能（在多个失误）的halido配体必须从铜离子释放的途中，以再生活性催化剂的Cu我L.在这项工作中，我们研究了铜的动力学I LX / Cu I L平衡，其中L是三齿N，N，N '，N ''，N ''-五甲基-二亚乙基三胺（PMDETA）。使用电化学分析，我们发现活性催化剂Cu I L的形成速率强烈依赖于溶剂。我们证明这个简单的配体交换反应的动力学和热力学在整个反应途径中都是至关重要的。

• Synthesis and structural analysis of a new polymorph of [Cu^II(PMDETA)Br₂]

  A new polymorph of [Cu-II(PMDETA)Br-2] has been recognized and characterized by X-ray structural studies at two different temperatures (120 and 298 degrees K). The results indicated the existence of a monoclinic crystalline system for [Cu-II(PMDETA)Br-2] grown in CH3OH or CH3CN with a distorted square pyramid geometry. The supramolecular structure of this complex has been studied using geometrical and Hirshfeld surface analysis. From lattice energy calculation, it has been shown that the newly found polymorph is thermodynamically more stable than the previously recognized one. UV-vis spectroscopy confirmed complex formation between (CuBr2)-Br-II and PMDETA in CH3OH and CH3CN, which was accompanied by peak displacement. FTIR spectroscopy, differential scanning calorimetry, and scanning electron microscopy were also used to get insights about the formation of this new polymorph of [Cu-II(PMDETA)Br-2].

  Copper polyamine complexes are among the most utilized catalysts for controlled radical polymerization reactions. Copper(I) complexes may react reversibly with an alkyl halide to form an alkyl radical, which promotes polymerization, and a copper(II) halido complex in a step known as activation. The kinetics of the reverse reaction between the alkyl radical and higher oxidation-state copper complex (deactivation) are less studied because these reactions approach diffusion-controlled rates, and it is difficult to isolate or quantify the concentration of the alkyl radical (R-center dot) in situ. Herein we report a broadly applicable electrochemical technique for simultaneously measuring the kinetics of deactivation and kinetics of activation.

  Further improvements have been made in processes for controlled polymerization of free radically (co)polymerizable monomers mediated by a transition metal complex participating in a redox reaction which involves transfer of a radically transferable atom or group to and from an initiator or dormant polymer and the growing active polymer chain ends. Two improvements involve the choice of counterion in the transition metal complex. In one improvement the transition metal is held in close conjunction with a solid support through interaction with a counterion directly attached to the support. This cognition also allows for improvements in catalyst utilization including catalyst recovery and recycle. In another improvement, particularly suitable for controlled polymerization of certain monomers with an expanded range of transition metals, the function of counterion and ligand in the development of the transition metal based catalyst is superseded by use of salt containing a soluble organic counterion. These and other process improvements have been employed to prepare and extended range of novel polymeric materials and novel processes for the preparation of functional polymers including a novel catalytic Atom Transfer Coupling Reaction.
