activation energies of various hydridetransferreactions was developed according to transition state theory using the Morse-type free energy curves of hydride donors to release a hydride anion and hydrideacceptors to capture a hydride anion and by which the activation energies of 187 typical hydride self-exchange reactions and more than thirty thousand hydride cross transferreactions in acetonitrile were

Kinetics of ferricyanide-mediatedoxidation of various 1-(4-substituted phenyl)-1,4-dihydronicotinamides were studied assuming either a rate determining initial electron loss or a rate determining proton loss following a rapid pre-equilibrium step. Values obtained using both methods were similar. In addition, vertical ionization potentials generated using the AM1 molecular orbital approximation were
