An improved protocol was described for the amination of chloroarenes with diarylamines under NiCl2(PCy3)2 catalysis in the presence of a Grignard reagent as base. This method fully suits bromo-/iodoarene substrates as well, and even is expanded to certain aryl tosylates. A preliminary investigation into the mechanism suggests that this amination reaction might proceed through NiI and NiIII intermediates rather than via the usually expected Ni0–NiII cycle.
在以格氏试剂为碱的条件下,描述了一种在 NiCl2(PCy3)2 催化下将氯代烯烃与二芳基胺胺化的改进方案。这种方法也完全适用于溴/碘烯烃底物,甚至可以扩展到某些芳基对甲苯磺酸盐。对其机理的初步研究表明,这种胺化反应可能是通过 NiI 和 NiIII 中间体进行的,而不是通常预期的 Ni0-NiII 循环。

In this paper, the solubility of selected arylamine molecules in methanol, hexane, and benzene has been investigated. Solubility of mmmTTA in hexane and benzene is the highest while mTTA has the lowest solubility in benzene and hexane. The UNIFAC and the UNIQUAC binary adjustable parameters have been determined. On the basis of these parameters, the solubility of these molecules has been predicted
