Ruthenium-catalyzed ortho-selective acylation of arylpyridines with acyl chlorides via C–H bond cleavage is described. Aromatic acyl chlorides as well as α,β-unsaturated acyl chlorides were coupled with arylpyridines to give aromatic ketones in the presence of [RuCl2(PPh3)3] as a catalyst and potassium carbonate as a base.
描述了钌催化的芳基吡啶与酰氯的邻位选择性酰化反应,通过C–H键的断裂实现。芳香酰氯以及α,β-不饱和酰氯与芳基吡啶偶联,生成芳香酮,催化剂为[RuCl2(PPh3)3],碱为碳酸钾。
