DOI: 10.1021/acsomega.5c04396
Abstract: Selective mono- or diaminations of 2,6-dibromopyridine were performed using microwave irradiation with water as solvent in 2–2.5 h. The only significant difference between the syntheses was the inclusion of K2CO3 as base and CuI/DMPAO catalyst… read more here.
