Visible-light-promoted synthesis of secondary and tertiary thiocarbamates from thiosulfonates andN-substituted formamides

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.

Cyanuric chloride: an efficient reagent for the Lossen rearrangement

An efficient method for the Lossen rearrangement that uses 2,4,6-trichloro-1,3,5-triazine (TCT) as a promoter is reported. This procedure allowed the preparation of various carbamates, thiocarbamates, and ureas in good yields directly from the correspondi

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.

Contra-thermodynamic trans-esteripication of carbamates by counter-attack strategy: A viable non-phosgene, non-mic route to carbamate pesticides

Treatment of methyl N-methylcarbaaate (1, R= Me) with phosphorus oxychloride and 1-naphthol results in the formation of the transesterified product, 1-naphthyl N-methylcarbamate (2, Ar=1-naphthy 1) in good yield. Similarly, ethyl N-methylthiocarbamate (5) is converted to 1-naphthyl N-methylcarbamate (2, Ar= 1-naphthyl) on treatment with phosphorus oxychloride and 1-naphthol. The mechanism of these interesting and industrially important transformations is discussed.
