Abstract

In this paper we describe the synthesis and the characterization of a series of cyclophosphazenes substituted with 2-oxazoline-containing moieties, with and without optical activity. These products could be obtained by reacting cyclophosphazenes containing six (hexachlorocyclophosphazene, C-6-Cl), two (2,2-dichloro-4,4,6,6-bis[spiro(2′,2″-dioxy-1′, 1″-biphenyl)]cyclophosphazene, C-2-Cl) and one (pentakis(phenoxy) monochlorocyclophosphazene, C-1-Cl) chlorine atoms, respectively, with a series of 4-hydroxyphenyl-2-oxazolines, as obtained by condensation reaction of methyl-4-hydroxybenzoate with 2-aminoethanol and with chiral and racemic 1-amino-2-propanol, and successive cyclization reactions of the resulting hydroxyamides to 2-oxazoline compounds.
