A continuous-flow photocatalytic synthesis of the industrially important thiuram disulfides has been developed, utilizing O2as 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.
Iodine mediated direct coupling of benzylic alcohols with dithiocarbamate anions: An easy access of S-benzyl dithiocarbamate esters under neat reaction condition

An efficient, metal and solvent free synthesis of S-benzylic dithiocarbamate esters has been demonstrated via the iodine mediated direct C-S coupling of benzylic alcohols with dithiocarbamate anions generated in-situ by the reactions of amines and carbon disulphide. All the reactions were very fast (15–30 min) and performed under open air atmosphere. Cyclic and acyclic secondary amines, primary amine, aromatic amine actively participated in the one-pot coupling reactions with different benzylic alcohols. Non benzylic alcohols offer the synthesis of O-thiocarbamate compounds under the identical reaction condition.

A one-pot three-component route for the synthesis of S-trifluoromethyl dithiocarbamates by the reaction of secondary amines, carbon disulfide and Togni's reagent is described. The reactions proceed in moderate to good yields. A similar reaction using a primary aliphatic amine afforded the corresponding isothiocyanate in high yield. A variable temperature NMR study revealed a rotational barrier of 14.6, 18.8, and 15.9 kcal/mol for the C-N bond in the dithiocarbamate moiety of piperidine, pyrrolidine, and diethylamine adducts, respectively. In addition, the calculated barriers of rotation are in reasonable agreement with the experiments.
