and alkyl amines without adding any photocatalysts, transition-metal catalysts, or ligands. A novel photoactivated electron donor–acceptor complex was proposed as the key intermediate. This protocol offers a new approach towards di-aryl dithiocarbamates, thus promising their potential applications in pharmaceutical chemistry and sulfur chemistry.

An eco-friendly and convenient method is developed herein for the synthesis of S-aryl dithiocarbamates via visible-light-induced SET process of an EDA complex between thianthrenium salt functionalized 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 functionalization
本文开发了一种环保且方便的方法,用于在温和的水性胶束条件下,通过可见光诱导的铊盐官能化芳烃和二硫代氨基甲酸根阴离子之间的 EDA 络合物的 SET 过程来合成S-芳基二硫代氨基甲酸盐。该策略间接实现了通过芳烃的位点选择性CH官能化构建S-芳基二硫代氨基甲酸酯的方法。最重要的是,反应在没有添加任何光催化剂的情况下顺利进行,并且副产物噻蒽大量回收利用,最终最大限度地减少了化学废物的产生。该方案为构建有价值的S提供了一个有前途的合成候选方案-芳基二硫代氨基甲酸酯,这也为胶束光催化开辟了新途径。

The Ullmann-type coupling reaction of sodium dithiocarbamates with aryl iodides and vinyl bromides catalyzed by CuI/N,N-dimethylglycine proceeds smoothly in DMF at 110 degrees C to give corresponding dithiocarbarnates in good yields. (c) 2007 Published by Elsevier Ltd.
