A simple and efficient method for the conversion of alcohols and phenols to primary O-thiocarbamates and S-thiocarbamates in the absence of solvent (solvent-free condition) using silica sulfuric acid (SiO2OSO 3H) as a solid acid is described. The products are easily distinguished by IR, NMR and X-ray data. X-ray data of the compounds reveal a planar trigonal orientation of the NH2 nitrogen atom with the partial C,N double-bond character and the CS or CO groups in synperiplanar position with CarylO and CalkylS moieties, respectively. Moreover, the OCSNH2 group which is perpendicular to the plane of the benzene ring in 1c and the central thiocarbamate SCONH2 group in 2b are essentially planar.

Seven new substituted 5-phenoxy-1,2,4-dithiazole-3-ones were prepared in modest yield (53-76%) from corresponding O-phenyl thiocarbamates and chlorocarbonylsulfenyl chloride in dry ether at-10 °C. All of the compounds were characterized by NMR and elemental analysis and some of them by X-ray diffraction. Preliminary kinetic measurements showed that the parent 5-phenoxy-1,2,4-dithiazole-3-one is a very efficient sulfurizing agent toward triphenyl phosphite. Copyright
