A novel molecular iodine-catalyzed protocol for the construction of thiocarbamates from readily available sodium sulfinates, isocyanides, and water has been described. The present methodology offers a facile and practical route to a variety of thiocarbamates in moderate to good yields with favorable functional group tolerance by use odorless sodium sulfinates as the sulfur source. The mechanistic studies suggest the present transformation involves a radical process.

An electrochemical oxidative synthesis of S-thiocarbamates by a carbamothioation reaction via a three-component coupling reaction (disulfide, water and isocyanide) is developed, which avoids the use of external oxidants and generates only hydrogen gas as the by-product. With NH4I as the mediator and electrolyte, the desired S-thiocarbamates were obtained in good yields in an undivided cell at room temperature.

The invention belongs to the field of synthesis of a compound, relates to a preparation method of a thiocarbamate compound, in particular to a method for synthesizing thiocarbamate through reacting ofcatalyzing three components of sodium sulfinate, isonitrile and water by iodine. The method comprises the following steps: adding the sodium sulfinate, the isonitrile and the water into ethyl acetate, then adding a molecular iodine catalyst and a phosphite reducing agent, heating, stirring and reacting for 6 to 10 hours under a condition that the temperature is 80 to 100 DEG C, and extracting, separating and purifying after finishing the reaction, thus obtaining the thiocarbamate. According to the method disclosed by the invention, the isonitrile is adopted as a carbon source, so that poisonous photogene and carbon monoxide are prevented from being used; odorless sodium sulfinate is adopted as a sulfur source, so that odorous thiophenol or thiol is prevented from being used; non-metalliciodine is adopted for catalyzing, so that a metal reagent is prevented from being used; the reaction has the advantages that the operation is simple and convenient, the technology is safe, environmentfriendliness is realized, and the like.

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 acid esters, and carboximidothioic acid esters.
