- W2109307976 abstract "The preparation of dicumylbarium by reaction of methyl cumyl ether with finely-divided barium in tetrahydrofuran (THF) and tetrahydropyran (THP) is described. The salt was characterized by spectrophotometric and chemical methods. Conductance studies for 10−3 to 10−5M concentrations of the salt in THF at temperatures from 15 to −70°C and in THP from 15 to −30°C demonstrated the presence of triple ions in thermodynamic equilibrium with free ions and pairs. In THF the dissociation constant varies from 1.0 × 10−9M at 15°C to 2.3 × 10−9M at −70°C, the corresponding enthalpy and entropy of reaction being −1.1 kcal mol−1 and −45 e.u. respectively. In THP, however, dissociation of the salt is too weak to be determined directly. Kinetic studies of the protonation reaction between dicumylbarium and triphenylmethane in THF showed that the apparent rate of reaction is 1.65 × 10−5 sec−1, independent of carbanion concentration. This indicates that protonation proceeds exclusively via free ions and hence provides further evidence for the presence of triple ions in dicumylbarium solutions." @default.
