  3. Abstract:
  4. A calorimetric method is described for the determination of the hydride affinities, ΔHmath image(R+) of seven dioxolenium ions from the title compounds and also tropylium, trityl and 9-phenyl xanthylium cations by hydride transfer to the carbocations from BH3CN−. Cyclic voltammetric methods yield free energies for reduction of the cations to the conjugate radicals and to the carbanions. The ΔHmath image(R+) values correlate well with the first reduction potentials of the cations
