  摘要：

  研究了在氯化亚铜存在下七种位阻酰基氯RCOCl对乙基溴化镁的反应性。除酮RCOEt外，还通过自由基反应生成化合物RCOCOR，RCOR，RR，RH和R（= H）。在卤化亚铜存在下，R'MgX与iPr 2 CHCOCl的缩合反应通过烷基铜物质R'Cu.MgXX'与酰氯反应生成酮RCOR'。自由基过程是通过烷基铜中间体的分解而引发的。研究了在最佳酮化条件下温度，溶剂和结构对烷基铜稳定性的影响。通过合成9种受阻酮iPr 2 CHCOR'可以具体证明这一点，其中Me⩽R'⩽Et 3C和Tr。

  The nickel(II) complex of a bulky pincer-type ligand, N,N′-bis(2,6-diisopropylphenyl)-2,6-pyridinedicarboxamido, was examined for sp3–sp3 coupling of Grignard reagents with polychlorinated solvents. The nickel(II) complex catalyzed CC coupling of polychlorinated alkyl halides, such as dichloromethane (CH2Cl2), chloroform (CHCl3), and carbon tetrachloride (CCl4), with various Grignard reagents. The

  检查了大钳形配体N，N'-双（2,6-二异丙基苯基）-2,6-吡啶二甲酰胺基的镍（II）配合物与多氯溶剂的格氏试剂的sp 3 –sp 3偶联。镍（II）络合物通过各种格氏试剂催化多氯代烷基卤化物（例如二氯甲烷（CH 2 Cl 2），氯仿（CHCl 3）和四氯化碳（CCl 4））的CC偶联。在环境反应条件下并在短时间内（20分钟）内进行了多个CCl键的有效活化。该催化剂显示出该反应类型迄今报道的最高活性，催化剂负载量低至0.4 mol％，周转频率（TOF）高达724 h-1。对于正在研究的所有多氯代溶剂，该催化剂均能够通过CC键形成取代所有氯原子。催化过程可能被证明是补救有毒多氯溶剂的有效方法，同时可产生合成和商业上重要的化学物质。

  A novel iron(III) complex (2) of a pincer ligand [1, N2,N6-bis(2,6-diisopropylphenyl)pyridine-2,6-dicarboxamide] was developed and used for remediation of polychlorinated solvents via sp(3)-sp(3) coupling of Grignard reagents with C-Cl bonds. The use of an iron catalyst for such coupling reactions is highly desirable due to its greener and more economical nature. Complex 2 was characterized using various spectroscopic techniques: electrospray ionization mass spectrometer (ESI-MS, m/z 575.1), cyclic voltammetry (E-1/2, 0.03 V and Delta E, 0.97 V), and ultraviolet visible (UV/Vis) spectroscopic techniques. The iron(III) complex showed efficient activation of multiple C-Cl bonds and catalyzing C-C coupling of polychlorinated alkyl halides, such as dichloromethane (CH2Cl2), chloroform (CHCl3), and carbon tetrachloride (CCl4), with various Grignard reagents under ambient reaction conditions. Complex 2 showed exceptional activity with reactions approaching near completion in about 5 min. With the required catalyst loading as low as 0.2 mol%, considerably high turnover numbers (TON = 483) and turnover frequency (TOF = 5,800 h(-1)) were obtained. None of the products detected during the reaction contained any chlorine, indicating an efficient dechlorination method while synthesizing products of synthetic and commercial interest. Interestingly, the catalyst was capable of replacing all chlorine atoms in each polychlorinated solvent under the investigations with high conversion.
