Reactions of 2, 3-dibromonaphthalene-1, 4-dione and pyridyl amines: X-ray structures, dft investigations, and selective detection of the hg2+ and ni2+ ions

Abstract

In thiswork, the productsformedbythe reaction between 2,3-dibromonaphthalene-1,4-dione with (pyridine-2-yl)methanamine and (pyridine-4-yl)methanamine are discussedin detial. The products 2-amino-3-bromonaphthalene-1,4-dione (A) and 2-aminonaphthalene-1,4-dione (B(1)) obtained are characterized through 1H and 13C-NMR, FTIR,mass spectrometry, single-crystal X-ray diffraction experiments, which arein conjunction with wB97X based density functional theory. compound Acan effectively and selectively detect Hg2+and Ni2+ions, and proposes a potential mechanism of action.
