Template reactions of aziridine and N-(2-aminoethyl)aziridine in nickel(II) and copper(II) formaldehyde complexes in the presence of nitroalkanes or ammonia

Aziridine and its dimer, N-(2-aminoethyl)aziridine, are perspective ligsons for the template synthesis in nickel(II) and copper(II) complexes of a new type of polyaza macromolecules by assembly reactions with formaldehyde in the presence of nitroalkanes or ammonia. The first common stage in this pro cess is the formaldehyde-initiated intraspherical conversion of N-(2-aminoe thyl)aziridine to piperazine. Then a template synthesis of polyaza macromol ecules takes place, in which N-(2-aminoethyl)aziridine or piperazine molecu les are linked to each other by groups formed by condensation of formaldehy de with nitroalkanes or ammonia. The resulting polyaza macromolecules can h ave a chain (polymeric) or a cyclic structure.
