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
合成了一系列的(1,2-二芳基乙烯基)膦配体,并制备了它们的钌配合物。的结构[(1,2-二苯基乙烯基)膦](η 6 -cymene)的RuCl 2(C1)通过X-射线结晶学证实。钌(1,2-二芳基乙烯基)膦配合物是用于2-芳基吡啶与一系列芳基氯化物(富电子和贫电子芳族氯化物)直接邻位芳基化的高效催化剂。通过芳香环上CH键的官能化,高度可控地形成单芳基化和二芳基化。
