  配体电子微调及其对铜光催化氮杂-亨利反应的光催化活性和机理的影响

  摘要：

  带有[2,9-二甲基-1,10-菲咯啉二亚胺（N ^ N）配体的[Cu（N ^ N）（P ^ P）] +形式的六个结构相关的杂铜（I）配合物家族合成了一系列电子可调的黄药（P ^ P）配体，并对它们的光电性能进行了表征。这些复合物中的铜纳米TiO2光催化氮杂亨利反应的反应性Ñ对-苯基四氢异喹啉进行了评价，同时对相关的激发态动力学进行了全面的研究。通过微妙地改变结构上可忽略的P ^ P配体的供电子特性，我们可以定制光氧化还原特性并将其与反应性联系起来。此外，取决于催化剂的退出状态氧化还原电势，优选的机理可以在还原性猝灭，能量转移和氧化性猝灭途径之间转换。对铜（I）光催化剂的结构调制，光电性能和光催化反应性的综合研究，使人们对光催化剂的合理设计以及竞争性光诱导电子和能量转移机制的复杂性有了更清晰的认识。

  Variation of Xantphos-Based Ligands in the Palladium-Catalyzed Reaction of Aryl Halides with Ureas

  摘要：

  A series of Xantphos-based ligands containing various substituents in the diphenylphosphino groups were synthesized, and their effect on the product yield and ratio in the palladium-catalyzed arylation of ureas with nonactivated aryl halides was studied. The arylation of urea and phenylurea in the presence of Pd-2(dba)(3)-CHCl3, 3,5-(CF3)(2)Xantphos, and Cs2CO3 in dioxane at 100degreesC gave the corresponding N,N'-diaryl-ureas in 62-98% yield.

  SO(2) efficient: A three‐component palladium‐catalyzed coupling of aryl lithium compounds; sulfur dioxide (provided by the easy‐to‐handle solid surrogate, DABSO); and aryl, heteroaryl, and alkenyl (pseudo)halides yields a diverse library of sulfones. An electron‐poor XantPhos‐type ligand suppresses aryl–aryl exchange and is key to obtaining high yields.

• Variation of xanthene-based bidentate ligands in the palladium-catalyzed arylation of ureas
  作者：Alexey G. Sergeev、Galina A. Artamkina、Irina P. Beletskaya

  DOI：10.1016/s0040-4039(03)01051-7

  日期：2003.6

  A series of xanthene-based bidentate ligands containing various substituents on diphenylphosphino groups were synthesized and tested in the palladium-catalyzed arylation reaction of urea with unactivated aryl bromides. It was found that both steric and electronic properties of the ligands have a pronounced effect on the yields and ratios of the products. Arylation of urea and phenylurea with unactivated aryl bromides in the presence of Pd(2)dba(3)-CHCl3/3,5-(CF3)(2)Xantphos and CS2CO3 as base in dioxane at 100degreesC gave the corresponding NN'-diarylureas in 62-98% yields.
