Novel cationic 1,2,4-selenadiazoles: synthesis addition of 2-pyridylselenyl halides to unactivated nitriles, structures and four-center Se N contacts

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...

Summary: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. 2-Pyridylselenyl halides undergo facile coupling with a triple CN bond of unactivated nitriles.
