Scientific seminar «Novel cationic 1,2,4-selenadiazoles: synthesisviaaddition of 2-pyridylselenyl halides»
22 October at 15:00 MSK
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. Cationic 1,2,4-selenadiazoles form supramolecular dimers in the crystal via Se⋯N chalcogen bonding, which was studied theoretically.
