Abstract The reaction of aryl-substituted cycloalka[b]thiopyrylium salts, as well as their O and N analogs, with bases (pyridine, NaOH, NaHCO3) was studied. The formation of 6,6′,7,7′-tetrahydro-2,2′,4,4′-tetraarylbis(5H-1-benzothiopyrans) through the intermediate anhydro bases was established for the cyclohexa[b]thiopyrylium salts, while the formation of 2,4-diphenyl-7-(2,4-diphenyl-8-cyclopenta[b]thiopyranyl)-Δ7,8-cyclopenta[b]thiopyran was established for 2,4-diphenylcydopenta[b]thiopyrylium perchlorate. The peculiarities of the behavior of the O and N analogs of the cycloalka[b]thiopyrylium salts in reactions with bases were ascertained. The investigation was carried out using electronic, IR, and PMR spectroscopy.
