Jafarpour, Farnaz published the artcilePalladium-catalyzed chelation-assisted C-H bond halogenation: selective chlorination of 2-arylpyridines with acid chlorides, SDS of cas: 85237-71-4, the publication is Synthesis (2014), 46(9), 1224-1228, 5 pp., database is CAplus.
Palladium-catalyzed chelation-assisted C-H bond halogenation of arenes using acid chlorides as chlorinating agents is reported. E.g., in presence of PdCl2 and CuCl2 in 1,4-dioxane at 140 °C, regioselective chlorination of 2-phenylpyridine by PhCOCl gave 92% I. This method provides a monoselective, straightforward, and clean route for the construction of aryl chlorides as privileged motifs in organic transformations.
