This grant in the Organic Dynamics Program provides support for                 the continuing research of Dr. William Dolbier of the                           University of Florida. The thrust of the research is the study                  of the unique kinetic and thermodynamic effects of fluorine                     substituents on the mechanisms of thermal homolytic and                         pericyclic reactions.                                                                                                                                           Experiments have been designed which will provide a fundamental                 understanding of the origin of the previously observed dramatic                 substituent effects. Included are experiments designed to test                  the influence of substituent mass upon the rotational component                 imparted during carbon-carbon bond cleavage and a test of the                   feasibility of tuning the thermodynamics of electrocyclic                       equilibria.  Innovative mechanistic probes such as high                         pressure techniques, kinetic isotope effects, stereochemical                    probes, solvent effect studies and correlation of theory with                   experiment will be employed to study the mechanisms of                          electrocyclic reactions, (2+2), (2+4) and 1,3-dipolar                           cycloadditions and a number of reactions involving homolytic                    formation of diradicals.
