Photoinduced Transition-Metal-Free Chan–Evans–Lam-Type Coupling: Dual Photoexcitation Mode with Halide Anion Effect

Autor: Zijun Zhou, Jeonguk Kweon, Hoimin Jung, Dongwook Kim, Sangwon Seo, Sukbok Chang

Publikováno v: Journal of the American Chemical Society. 144:9161-9171

Herein, we report a photoinduced transition-metal-free C(aryl)-N bond formation between 2,4,6-tri(aryl)boroxines or arylboronic acids as an aryl source and 1,4,2-dioxazol-5-ones (dioxazolones) as an amide coupling partner. Chloride anion, either gene

Quantitative Analysis on Two-Point Ligand Modulation of Iridium Catalysts for Chemodivergent C–H Amidation

Autor: Yeongyu Hwang, Dong-Wook Kim, Hoimin Jung, Euijae Lee, Sukbok Chang

Publikováno v: Journal of the American Chemical Society. 142:8880-8889

The transition-metal-catalyzed nitrenoid transfer reaction is one of the most attractive methods for installing a new C-N bond into diverse reactive units. While numerous selective aminations are known, understanding complex structural effects of the

Brønsted acid catalysis of photosensitized cycloadditions

Autor: Dasol Cho, My-Hyun Baik, Evan M. Sherbrook, Tehshik P. Yoon, Hoimin Jung

Publikováno v: Chemical Science

Catalysis is central to contemporary synthetic chemistry. There has been a recent recognition that the rates of photochemical reactions can be profoundly impacted by the use of Lewis acid catalysts and co-catalysts. Herein, we show that Brønsted aci
