Nickel-catalysed synthesis of 3-chloroanilines and chloro aminopyridines via cross-coupling reactions of aryl and heteroaryl dichlorides with amines
摘要:
Selective monoamination of aryl and heteroaryl dichlorides has been carried out using a catalyst combination of Ni(0) associated to 2,2'-bipyridine. The synthesis of novel 3-chloroanilines and chloro aminopyridines in good to excellent yields is allowed using an excess of amine, 10 or 20 mol% catalyst and short reaction times.
