Scientific seminar «Novel cationic 1,2,4-selenadiazoles: synthesisviaaddition of 2-pyridylselenyl halides»
2-Pyridylselenyl halides undergo facile coupling with a triple CN bond of unactivated nitriles. Unprecedented heterocyclization allowed the preparation of a novel class of cationic 1,2,4-selenadiazoles in remarkably high yields.
