Abstract
Ion pair acidities are reported in tetrahydrofuran (THF) solution for the lithium and cesium salts of several sulfones and one sulfoxide. Th ese salts are shown to be monomeric in the THF solutions studied. Ther modynamic constants are reported for several salts. The results and so me conductivity studies show that both the lithium and cesium salts ar e contact ion pairs in THF. Because of ion association the relative pK s are slightly lower for cesium salts and much lower for lithium salts than fbr the free ions in DMSO solution. (C) 1997 Elsevier Science Lt d.
