“…224 More recently, Rao greatly contributed to expanding the scope of substrates that can be used in cross-coupling reactions with organobismuth reagents. For instance, his group developed procedures to cross-couple triarylbismuthines with aryl iodides, triflates and bromides, 225 halogenated furans, 226 thiophenes 227 and benzofurans, 228 iodochromones, 229 bromo and trifluoromethanesulfonyloxy coumarins, 230 chlorocoumarins, 231 bromoquinones, 232 halobenzaldehydes, 233 bromochromones, 234 chloroquinolines and chloro/iodo pyridines, 235 bromotrifloxycoumarins 236 and CTV-I 3 237 (Scheme 39 B). We reported in 2016 protocols to cross-couple highly functionalized triarylbismuthines with various electrophiles such as aryl iodides and bromides, iodofurans, chloro-and bromopyridines, chloropyrimidines, pyrazines and pyridazines.…”
