OXIDATION IMINATION OF SULFENYL CHLORIDES BY N-CHLOROCARBOXAMIDES. N-ACYLSULFINIMIDOYL CHLORIDES

Dubinina, T. N.,Levchenko, E. S.,Zabolotnaya, T. G.

, p. 143 - 148 (2007/10/02)

The reaction of arenesulfenyl chlorides ArSCl with N-chlorocarboxyamides in a ratio of 1:1 leads to the formation of N-acylsulfinimidoyl chlorides ArS(=NCOR)Cl.The reaction of arenesulfenyl chlorides and N-chlorobenzamide in ratio of 1:1 leads to aryldibenzamidosulfonium chlorides ArS(NHCOC6H5)2, which are hydrolyzed with the formation of N,N'-benzoylarenesulfinamidines ArS(=NCOC6H5)NHCOC6H5 and are cleaved into acid chlorides and benzamide when heated.
