Substituent Effects in Radical Chemistry ISBN: 9789401086141 |
| Popis: |
The role of substituent effects in free radical and carbene chemistry was investigated using a variety of techniques including e.s.r. spectroscopy, measurement of appearance energies, electrochemistry and kinetics. The thermodynamic data obtained in some of these experiments were used to probe the magnitude of substituent effects and their impact on group additivity methods. Electrochemical experiments showed that the removal of an electron from a substituent had a profound effect on the strengths of the neighbouring C-H bonds. Finally, examples drawn from carbene chemistry showed that sterically crowded substituents could be used to induce major electronic changes in these molecules. |
