A new method of ortho-fluorination where an aryl C—H bond is directly replaced by an aryl C-F bond in a palladium-catalyzed reaction is provided. The method includes the ortho-fluorination of a triflamide protected benzylamine, a palladium catalyst, such as Pd(OTf)

, a fluorinating reagent such as N-fluoro-2,4,6-trimethylpyridinium triflate, and a ligand to promote the reaction such as N-methylpyrrolidinone (NMP).
提供了一种新的正氟化方法,其中芳基C—H键直接被芳基C-F键取代,在钯催化反应中实现。该方法包括对三氟甲基保护苄胺进行正氟化处理,使用钯催化剂,如Pd(OTf)2,氟化试剂,如N-氟-2,4,6-三甲基吡啶三氟甲磺酸盐,以及用于促进反应的配体,如N-甲基吡咯烷酮(NMP)。
