Abstract
Tertiary (2H-azirin-2-yl)ammonium salts were prepared from methyl 2-halo-3-aryl-2H-azirine-2-carboxylates and 1,4-diazabicyclo[2.2.2]octane in very good to excellent yields. Both iodide and bromide salts are stable enough in crystalline form to be stored in a freezer for up to several months. The structures of the obtained salts were confirmed by NMR spectroscopy and HRMS.
