A simple synthesis of [NS]+[AlCl4]– and the insertion reaction with alkylselenium halides: X-ray structure of [N2S2SeCl]+[AlCl4]–

Abstract

The reaction of (NSCl)₃ with aluminium trichloride at 50 °C without solvent, preferably with ultrasonic irradiation, produces [NS]⁺[AlCl₄]^– in good yields; the thiazyl salt reacts with alkylselenium halides to give [N₂S₂SeCl]⁺[AlCl₄]^–, in which the cation is shown by X-ray crystallography to be a five-membered ring with chlorine attached to selenium.
