I 2 as a mild and efficient catalyst in deoxygenation of sulfoxides with thioacetic acid
An effective procedure for deoxygenation of sulfoxides to sulfides using thioacetic acid as a reducing agent and a catalytic amount of I2 in MeCN at ambient temperature has been developed. Using this protocol, a variety of sulfoxides including benzyl, allyl, alkyl and aryl sulfoxides have been successfully reduced to the corresponding sulfides in excellent yields.

Spectroelectrochemical study of the nucleophilic substitution of diacyl disulfides by 2-nitrophenyl thiolate ions in N,N-dimethylacetamide
S-Aryl thiol esters RC(O)SAr and ArS2- ions are the end products resulting from the reactions between bis(2-nitrophenyl) disulfide Ar2S2 and thiocarboxylate ions RC(O)S- (R = Me, Ph) at 20°C. The apparent SNAr process in fact occurs in two steps as shown by UV-vis absorption spectrophotometry coupled with voltammetry: (i) formation of diacyl disulfides [RC(O)]2S2 and ArS- ions by redox exchange; (ii) subsequent nucleophilic substitution of 2-nitrophenyl thiolate ions at the carbonyl carbon of diacyl disulfides.

Synthesis of isothiocyanates by reaction of amides with carbon disulfide in the presence of solid potassium carbonate/sodium hydroxide mixture
Readily available N-monosubstituted trifluoroacetamides are transformed into isothiocyanates in good yield by reaction, at room temperature, with carbon disulfide in acetonitrile in the presence of anhydrous sodium hydroxide/potassium carbonate basic mixture.
