In the reaction of N-arylthio-1,4-benzoquinone imines containing two potential reaction centers, i.e., the quinonoid ring and the =C=N-S- triad, with chllorine the products from chlorination of the quinonoid ring were isolated.On the basis of the experimental data a scheme is proposed for the chlorination of N-arylthio-1,4-benzoquinone imines.The electron-withdrawing characteristics of substituents in the arylthio group determine the degree of chlorination of the quinonoid ring.By x-ray fluorescence spectroscopy (XF spectroscopy) some parameters of the electronic structure of the sulfur atom and the effect of substituents in the arylthio group were determined for the N-arylthio-1,4-benzoquinone imines.
