An electron donor-acceptor photoactivation strategy for the synthesis of S -aryl dithiocarbamates using thianthrenium salts under mild aqueous micellar conditions

An eco-friendly and convenient method is developed herein for the synthesis of S-aryl dithiocarba-mates via visible-light-induced SET process of an EDA complex between thianthrenium salt functional-ized arenes and dithiocarbamate anions under mild aqueous micellar conditions. This strategy indirectly realizes the method for constructing S-aryl dithiocarbamates through site-selective C -H functionaliza-tion of arenes. Most importantly, the reaction proceeded smoothly without addition of any photocatalyst, and the by-product thianthrene is recycled in quantity, ultimately minimizing the production of chemical waste. This protocol provides a promising synthesis candidate for the construction of valuable S-aryl dithiocarbamates, which also opens up a new avenue for micellar photocatalysis.& COPY; 2023 Published by Elsevier B.V. on behalf of Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.
