An unprecedented palladium-catalyzed cyanation of aromatic C-H bonds by using tertiary amine derived isocyanide as a novel cyano source was developed. Cu(TFA)(2) was used as a requisite stoichiometric oxidant. Mechanistic studies suggest that a tertiary carbon cation-based intermediate is involved following the C-N bond breakage.
开发了一种前所未有的钯催化芳环 C-H 键氰化反应,使用叔胺衍生的异氰化物作为新型氰源。Cu(TFA)2 用作必需的化学计量氧化剂。机理研究表明,在 C-N 键断裂后,涉及到基于叔碳阳离子的中间体。
