Effect of alkali cations on the methoxide ion addition to corands incorporating a thiopyrylium subunit

Article abstract of DOI:10.1016/0040-4020(96)00029-4

The incorporation of a thiopyrylium ring in a corand structure forms a system with a weak binding ability in methanol towards the alkali cations K⁺, Rb⁺ and Cs⁺. The binding substantially increases in basic solution becaus
