Abstract

Abstract Three aromatic diamine-based benzoxazines were successfully prepared by a facile, clean, one-pot procedure from 1, 4-phenylenediamine (1), 4, 4′-diaminodiphenyl ether (2), and 4, 4′-diaminodiphenyl methane (3), respectively. Their structures were confirmed by NMR spectra and single crystal diffractogram. The effect of the reactivity of diamines on the purity of the resultant benzoxazines was discussed. The resultant ...
