Sulfonium salts are obtained by the reaction of cyclic sulfides with 1,4-benzoquinone and 5,8-quinolinedione in an acidic medium.It is shown by the method of concurrent reactions that the introduction of alkyl substituents into molecules of thiacyclopenta

, p. 726 - 730 (2007/10/02)
2,5-Dihydroxyphenylthioniacycloalkane salts were synthesized in a single stage by the reaction of quinone with cyclic sulfides.The crystal structures of 2,5-dihydroxyphenylthianium perchlorate and chloride hydrate were investigated by x-ray crystallographic analysis and IR spectroscopy.

A one-stage synthesis was realized for 2(3)-methyl-4-hydroxy-, 2,4-dihydroxy-, 2,3,4-trihydroxy-, and 2,5-dihydroxyphenylthiophanium chlorides by the reactions of substituted phenols with thiophane and chlorine.The yields (57-75percent) of the products varied in line with the activity of the phenols.
