Herein, we develop a metal-free, nondirected, site-selective, one-pot approach to meta-arylation of arylamines. This Brønsted acid-catalyzed, direct C–C bond formation offers a broad substrate scope and scalability and creates the ideal conditions for overriding the conventional site-selectivity to furnish meta-substituted anilines. Additionally, the protocol applies to the meta-allylation of anilines
在此,我们开发了一种无
金属、非定向、位点选择性、一锅法来进行芳基胺的间芳基化。这种布朗斯台德酸催化的直接 C-C 键形成提供了广泛的底物范围和可扩展性,并为超越传统的位点选择性以提供间位取代的
苯胺创造了理想的条件。此外,该方案适用于
苯胺的间位烯丙基化,并已扩展到提供药用特殊芳基化二胺和密集官能化
苯胺的后期功能化和合成。控制实验和密度泛函理论研究为所提出的机制和选择性提供了证据。
