Direct Carbo-Acylation Reactions of 2-Arylpyridines with α-Diketones via Pd-Catalyzed C–H Activation and Selective C(sp2)–C(sp2) Cleavage
摘要:
An efficient carbo-acylation reaction of 2-arylpyridines with alpha-diketones via Pd-catalyzed C-H bond activation and C-C bond cleavage in the presence of TBHP was developed that generated aryl ketones in good yields. The highly selective formation of aryl ketones was observed when 2-arylpyridines reacted with aromatic/aliphatic alpha-diketones.
