chelation‐assisted direct intermolecular arylation using an N‐heterocyclic carbene and phosphine ligands (see scheme; IMes=1,3‐bis(2,4,6‐trimethylphenyl)imidazol‐2‐ylidene). The reaction is operationally simple, proceeds under mild reaction conditions to afford mono‐ or diarylated products in excellent yields, and is applicable to the arylation at the sp3 or sp2 CH bonds of 2‐pyridyl‐containing aryl, vinyl
Rh-oadies加入:使用N-杂环卡宾和膦配体(见方案; IMes = 1,3-双(2,4,6-三甲基苯基)咪唑)开发了一种新的铑催化剂,用于螯合辅助的直接分子间芳基化-2-亚基)。该反应操作简单,在温和的反应条件下进行,得到单或diarylated产品以优良产率,并且适用于在SP的芳基化3或sp 2 ç 的含有2-吡啶基-芳基,乙烯基H键,或烷基部分。
