Continuous-flow step-economical synthesis of thiuram disulfides via visible-light photocatalytic aerobic oxidation

A continuous-flow photocatalytic synthesis of the industrially important thiuram disulfides has been developed, utilizing O2 as the oxidant and Eosin Y as the photoredox catalyst. This highly atom- and step-economical method features much reduced reaction time as well as excellent product yield and purity, making it a sustainable and potentially scalable process for industrial production.
