Basak, Shubhajit published the artcilePalladium-Catalyzed 2-fold C-H Activation/C-C Coupling for C4-Arylation of Indoles Using Weak Chelation, Application In Synthesis of 91-16-7, the publication is Organic Letters (2022), 24(2), 554-558, database is CAplus and MEDLINE.
Palladium-catalyzed weak chelation-assisted regioselective C4-arylation of indoles was accomplished using a readily available arene at moderate temperature The C4-arylation, weak chelating benzoyl (Bz) directing group, cross-dehydrogenative coupling (CDC), broad substrate scope, and late-stage diversifications were the important practical features.
