Abstract:
In the present study, reactions of spiro-N,N-diisopropylpropane-1,3-diamino-2,2–4,4 tetrachlorocyclotriphosphazatriene (1) with 2,2′-dihydroxybiphenyl (2), and 3-amino-1-propanol (3) have been investigated. Dispiro (4, 6) and trispiro (5) phosphazene derivatives were obtained from these reactions. New spirocyclotriphosphazenes (4–6) were characterized by elemental analysis, 1H, 13C and 31P NMR spectroscopy. © 2022 Elsevier B.V.
