Kozel V. Organylsulfur trifluorides containing Sulfur-Carbon bond

Pyridyl-2- and pyrimidinyl-2-sulfur trifluorides were synthesized. A convenient approach to dialkylamido sulfoxylic acid fluorides based on reaction of potassium fluoride with the corresponding acid chlorides has been developed. These compounds can be involved in stereo- and regioselective addition reactions to the C=C double bond. It was found that the reaction of arylsulfur trifluorides with (N-trimethylsilyl)isocyanate leads to the formation of (N-tluoroformyl)sulfinimidoyl fluorides. These can be used as starting compounds to the synthesis of new representatives of insufficiently known sulfur-containing heterocyclic compounds, 5-substituted-1-aryl-4H-[1,2,4,6]-thiatriazin-3-ones.
