Abstract
The relative rates of the leaving groups in free radical S(H)2' reactions h ave been determined. The order of the relative elimination rates of the lea ving group is: I > Br (14) > SPh (2) > Cl (1) >> OPh, SiMe3. This is consis tent with the bond dissociation energy of the C-X bond. The less the bond d issociation energy value is, the better the leaving group is.
