A general visible-light-promoted metal-free synthesis of secondary and tertiary thiocarbamates starting from thiosulfonates andN-substituted formamides is developed. By employing rhodamine B as a photocatalyst andtert-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 for 12 h.
Expanded Chemistry of Formamidine Ureas

(Equation presented) Formamidine ureas display a rich manifold of reactivity. Thiols induce substitution at the carbonyl carbon to give thiolcarbamates; base-mediated alkylation and acylation occurs at the terminal urea nitrogen, and a new fragmentation/acylation pathway has been uncovered with isocyanates.
