Haifeng Yu,Yong-Mei Zhang,Tiechun Li,Peiqiu Liao,Quanping Diao,Guang Xin,Qingling Meng,Dongyan Hou +7 more
TL;DR: In this paper, an efficient synthetic route to 3-aroyl-5-formyl-4-halo pyridin-2(1H)-ones has been developed via Vilsmeier cyclization of 2-(ethylthio(arylamino)methylene)-1-alkylbutane-1,3-dione.
Journal ArticleDOI
Theoretical interpretations of electronic and fluorescence spectra of new 2(1H)-pyridone derivatives in solution and solid state
TL;DR: In this paper, a combined experimental and computational study was performed for the spectroscopic properties of novel 2(1 H )-pyridones, which were found to be virtually nonfluorescence in solution while modestly fluorescent in solid state.

TL;DR: In this paper, the structure of 4H-3,1-benzothiazine-4-thiones was established by means of 13C-NMR analysis and X-ray crystallography.
Journal ArticleDOI
Transition metal free, green and facile halogenation of ketene dithioacetals using a KX–oxidant system
TL;DR: A facile oxidative halogenation of α-oxo ketene dithioacetals was achieved by using a potassium halide and oxidant combination under transition metal free conditions at ambient temperature.
