A synthesis of haloisoquinolines through electrophilic cyclisation involving an electrophilic-exchange process has been developed. A variety of 2-alkynylbenzylazides are cyclised in the presence of KX (X = I, Br, Cl) and electrophilic fluoride reagents, to afford the corresponding haloisoquinolines in moderate to good yields. Reagents for electrophilic halogenation have been generated from their
