detailed insight into the selectivity- and reactivity-controlling factors in bifurcated ruthenium-catalyzed direct C-Harylations and dehydrogenative C-H/C-Hfunctionalizations. Thorough investigations revealed the importance of arene-ligand-free complexes for the formation of biscyclometalated intermediates within a ruthenium(II/IV/II) mechanistic manifold.
实验和计算研究提供了对叉化钌催化的直接CH芳基化和脱氢CH / CH功能化中选择性和反应性控制因素的详细了解。彻底的研究表明,不含芳烃配体的络合物对于在钌(II / IV / II)机械歧管中形成双环金属化中间体的重要性。

were synthesized, and their ruthenium complexes have been prepared. The structure of [(1,2-diphenylvinyl)phosphine](η6-cymene)RuCl2 (C1) was confirmed by X-ray crystallography. Ruthenium (1,2-diarylvinyl)phosphine complexes are highly efficient catalysts for direct ortho arylation of 2-arylpyridine with a range of aryl chlorides (electron-rich and electron-poor aromatic chlorides). Highly controllable
