A simple and efficient procedure was developed for the synthesis of S -alkyl (aryl) thiocarbamates under solvent-free conditions without the use of a catalyst. The significant features of this protocol are (a) operational simplicity, (b) mild reaction conditions, (c) short reaction times, (d) solvent-free conditions, and (e) high product yields.

AbstractA catalytic route to carbamothioate derivatives through a reaction involving isocyanides, elemental sulfur, and aryl iodides has been developed. The reaction scope has been examined using a range of isocyanides and aryl iodides. The reactions involve two consecutive C–S bond formations. Control experiment revealed that the reaction proceeds through an iminium species. Graphic abstract

Direct reaction of isocyanides with some sulfenic-acid-generating sulfoxides led to the effective formation of the corresponding thiocarbamic acid S-esters in good to high yields. A multicomponent reaction involving isocyanide, sulfoxide, and a suitable nucleophile has also been developed, providing ready access to a diverse range of sulfur-containing compounds, including isothioureas, carbonimidothioic
A general visible-light-promoted metal-free synthesis of secondary and tertiary thiocarbamates starting from thiosulfonates and N-substituted formamides is developed. By employing rhodamine B as a photocatalyst and tert-butyl hydroperoxide (TBHP) as an oxidant, a wide scope of thiocarbamates can be obtained through direct thiolation of acyl C–H bonds under irradiation of blue light at room temperature
