A number of alkyl, aryl and bifunctional isothiocyanates are obtained in moderate to high yields (41-94%) in a two-step, one-pot reaction of the parent primary amines or their salts with carbon disulfide, followed by reaction of the thus formed dithiocarbamates with T3P (propane phosphonic acid anhydride) as a new and efficient desulfurating agent.

We have developed two green, practical, and efficient procedures, including a one-pot one, to synthesize isothiocyanates from amines and carbon disulfide via desulfurization with sodium persulfate. Water is used as the solvent. Basic conditions are necessary for good chemoselectivity for isothiocyanates. Structurally diverse linear and branched alkyl amines and aryl amines are readily converted to isothiocyanates by the two procedures in satisfactory yields. Halogens, benzylic C-H bonds, methylthio, nitro, ester, alkenyl, electron-rich or -deficient (hetero)aryls, acetylenyl, and even phenolic and alcoholic hydroxyls are well tolerated. The one-pot procedure in water can also be used to realize the preparation of chiral isothiocyanates from chiral amines, and the modification of bioactive structures with free amino groups. In large-scale preparation, simple and practical purification procedures independent of column chromatography are developed.

Two new 3-aryl-5-(4-nitrobenzylidene)-2-thioxothiazolidin-4-one derivatives (1 & 2) were synthesized by the Knoevenagel condensation reaction of 3-(4-aryl)-2-thioxo-1,3-thiazolidin-4-ones with 4-nitrobenzaldehyde. Both products were isolated as orange cry
