Selective C(sp2)−H Halogenation of "click" 4-Aryl-1,2,3-triazoles [PDF]

, 2017
Selective bromination reactions of “click compounds” are described. Electron-neutral and electron-deficient arenes selectively undergo unprecedented Pd-catalyzed C–H ortho-halogenations assisted by simple triazoles as modular directing groups, whereas ...

Triazole-Directed Pd-Catalyzed C(sp2)–H Oxygenation of Arenes and Alkenes [PDF]

, 2016
Selective Pd-catalyzed C(sp2)–H oxygenation of 4-substituted 1,2,3-triazoles is described. Unlike previous metal-catalyzed C–H functionalization events, which preferentially occur at the activated heterocyclic C–H bond, the regioselective oxygenation of ...
