The H/D kinetic isotope effecta and activation volumes have been measured for several hydrogen-transfer reactions using tetralin, dihydronaphthalenea, cyclohexa-l, 4-diene, and cyclohexanol as donors. The isotope effects were found to exhibit different patterns for reactions of different mechanisms. They indicate whether hydrogen is in transit in the activated complex and show the number of atoms in transit (one or two). The KIE for the ...
