Wang, Tao published the artcileA Metal-Free Direct Arene C-H Amination, Recommanded Product: 2-Methoxynaphthalene, the publication is Advanced Synthesis & Catalysis (2021), 363(11), 2783-2795, database is CAplus.
Here, a metal-free arene e.g., mesitylene C-H amination using hydroxylamine derivatives 4-(CH3)C6H5S(O)2ON(R)R1 (R = H, Me; R1 = Me, Boc, Bn, etc.) under benign conditions was reported. A charge transfer interaction between the aminating reagents and the arene substrates enables the chemoselective amination of the arene, even in the presence of various functional groups. Oxygen was crucial for an effective conversion and its accelerating role for the electron transfer step was proven exptl. In addition, this was rationalized by a theor. study which indicated the involvement of a dioxygen-bridged complex with a “Sandwich-like” arrangement of the aromatic starting materials and the aminating agents at the dioxygen mol.
