A method for direct, transition-metal-free ortho-arylation of anilines by aryl chlorides, bromides, fluorides, and triflates has been developed. This methodology provides the most direct approach to 2-arylanilines since no protecting or directing groups on nitrogen are required. The arylation is functional-group tolerant, with alkene, ether, trifluoromethyl, dimethylamino, carbonyl, chloro, and cyano
已经开发了一种通过芳基氯化物、溴化物、氟化物和三氟甲磺酸酯对苯胺进行直接、不含过渡金属的邻位芳基化的方法。这种方法提供了最直接的 2-芳基苯胺方法,因为不需要氮上的保护或导向基团。芳基化是官能团耐受的,可以耐受烯烃、醚、三氟甲基、二甲氨基、羰基、氯和氰基官能团。对映体纯联萘二胺的苯基化提供具有>99% ee 的产物。

often chosen for transitionmetalcatalyzed C-N coupling reactions. In this work, it was found that the use of alkane solvents (e.g. cyclohexane, heptane) allows for highly efficient Ni-catalyzed C-N coupling of aryl pseudohalides with different types of amines in the presence of NHC ligands. Excellent functional group tolerance was achieved. Stronger hydrogen bonding effect between amine NH moiety
