Sažetak

Studies on solvolytic reactions proceeding via neighboring group participation by means of secondary deuterium isotope effects are reviewed. The changes in magnitude of secondary KIEs are related to the degree of participation in the reaction transition state and these data are compared with other experimental evidence. Supporting information on the structure of carbocations is obtained by high level ab initio calculations. Isotope effect studies turned out to be among the most powerful tools available to chemists for elucidating the nature and structure of reaction transition states.
