Abstract
The equilibrium cesium ion pair acidities in tetrahydrofuran have been determined at 25 o C for 2-p-biphenylyl-1,3-dithiane (29.1), 2-phenyl-1,3-dithiane (30.5), 4-methyl-2,6,7-trithiabicyclo[2.2.2]octane(30.2), 1,3-dithiane (36.5), and 2-methyl-1,3-dithiane (38.2). Studies of their acidities over a wide range of concentrations indicate that these dithianylcesium salts exist as monomeric ion pairs in solutions with concentrations ranging from 10 -3 to 10 -5 M
