Аннотация:Intramolecular cyclization of adiponitrile with the formation of an amidinate functional group in zirconium coordination sphere was found. The obtained complex can be protolyzed with HCl in dioxane to afford a new representative of amidines, namely, 7-phenyl-1,3,4,5-tetrahydro-2H-azepin-2-imine in hydrochloride form.
