REACTIONS OF DISUBSTITUTED (IN THE PHENYL RING) ARYLTHIOLANIUM AND ARYLTHIANIUM SALTS WITH AMINES

Article abstract of DOI:10.1007/BF00633513

The reactions of 2(3)-methyl-4-hydroxy- and 2,4-dihydroxyphenylthiolanium salts with excess secondary amine (piperidine, morpholine) lead to the corresponding aryl aminobutyl sulfides.The amino sulfides formed on the basis of 2,5-dihydroxyphenylthiolanium and -thianium salts are unstable and require rapid treatment with acetic anhydride or HCl.The reaction of 2,4-dihydroxyphenylthiolanium and 2,5-dihydroxyphenylthianium salts with an equimolar amount of amine makes it possible to isolate the intermediate zwitterionic phenoxides.
