Proton-Initiated Conversion of Dithiocarbamates of 9,10-Anthracenedione
Proton-initiated conversion of dithiocarbamate derivatives of the 9,10-anthracenedione under conditions of acid-catalyzed cyclodehydration using the action of a mixture of H2SO4-AcOH and further treatment with perchloric acid was investigated. Based on the data of the spectral methods (1H, 13C NMR, IR, UV spectroscopy), it is established that the reaction stops at the stage of protonation of the sulfur atom of the thiocarbonyl group with the formation of perchlorates.
