Palladium-Catalyzed Oxidative Arylalkylation of Unactivated Alkenes: Dual C–H Bond Cleavage of Anilines and Acetonitrile
摘要:
A palladium-catalyzed oxidative arylalkylation of unactivated alkenes involving dual C-H bond cleavage of arene and acetonitrile was developed. This reaction was promoted by pyridine as a ligand, and the ratio of palladium to pyridine is vital for this transformation. A series of nitrile-containing indolines were efficiently provided in moderate to good yields.

photocatalytic cyanomethylarylation of alkenes with acetonitrile has been established using K-modified carbon nitride (CN-K) as a recyclable semiconductor photocatalyst. This protocol, employing readily accessible alkyl N-hydroxyphthalimide (NHPI) ester as a radical initiator, allows the efficient construction of a broad array of structural diverse nitrogenous heterocyclic compounds including indolines, oxindoles
使用 K 改性氮化碳(CN-K)作为可回收半导体光催化剂,建立了可见光介导的烯烃与乙腈的异相光催化氰甲基芳基化反应。该方案采用易于获得的烷基N-羟基邻苯二甲酰亚胺 (NHPI) 酯作为自由基引发剂,可以有效构建多种结构多样的含氮杂环化合物,包括二氢吲哚、羟吲哚、异喹啉酮和异喹啉二酮。
