Oparin, D. A.,Khodorkovskii, V. Yu.
, p. 141 - 149 (2007/10/02)
A convenient preparative method was developed for the synthesis of 1-H-thiophthalylium salts, including reduction of 1-alkylthio-substituted thiophthalylium tetrafluoroborates with sodium borohydride in anhydrous methanol and reaction of the obtained thio
SYNTHESIS OF 3,3-DISUBSTITUTED 2-THIOPHTHALIDES
Oparin, D. A.,Kuznetsova, A. S.
, p. 139 - 141 (2007/10/02)
The alkylation of 1-thiophthalides followed by treatment of the reaction mixture with triethylamine constitutes a convenient method of preparing 3,3-disubstituted 2-thiophthalides.
SYNTHESIS OF N-SUBSTITUTED 1-AMINOTHIOPHTHALYLIUM SALTS AND THEIR REACTIONS WITH NUCLEOPHILIC REAGENTS
Oparin, D. A.
, p. 149 - 153 (2007/10/02)
Previously unknown stable 1-methylarylaminothiophthalylium salts were synthesized by the alkylation of 1-aryliminothiophthalans by dimethyl sulfate, followed by treatment of the reaction mass with perchloric acid.The electrophilic activity of the obtained
