Abstract

Abstract: A novel heterocyclic diamine, 1,2-dihydro-2-(4-amino-phenyl)-4-[4-(4-amino-phenoxyl) phenyl](2H)phthalazin-1-one was synthesized. Its ¹H and ¹³C NMR spectra were completely assigned by utilizing the two-dimensional heteronuclear ¹³C-¹Hmultiple-bond coherence(HMBC) spectroscopy, and heteronuclear ¹³C-¹H one-bond coherence spectroscopy, homonuclear shift correlation spectroscopy(¹H,¹H-COSY) and the rotating frame overhauser enhancement spectroscopy(ROESY).The structure of the compound was proven to be phthalazinone instead of phthalazine ether.

Key words: Two-dimensional NMR, Phthalzinone, Assignment
