on the 2,4-diaminotriazine scaffold are described. These complexes are active catalysts for the Suzuki–Miyaura cross-coupling of a wide range of aryl, heteroaryl (including benzoxazole, thiazole, pyridine, pyrimidine, thiazole), primary and secondary alkyl halides, and pseudohalides with different organoboronate reagents giving excellent to good isolated yields. Neutral deprotonated complexes seem
描述了基于2,4-二氨基三嗪支架的空气稳定,热稳定且定义明确的阳离子Ni(II)PNP钳形复合物。这些络合物是Suzuki-Miyaura交叉偶联各种芳基,杂芳基(包括苯并恶唑,噻唑,吡啶,嘧啶,噻唑),伯和仲烷基卤化物和假卤化物的活性催化剂,具有不同的有机硼酸酯试剂,具有优异的质量。孤立的产量。中性去质子化的配合物似乎在催化过程中起关键作用。
