✦ Synopsis

No thermal substitutions of '*F for X (X = halogen atom) are obsened with CF,X and (CH&_&H,X substrates in ex&ss SF,. The absence of thermal yield increasing with weaker C-X bond energies, as found with CHjX substrates, is attributed to the much larger mass versus H of F and CH3 abstituents.

The thermal substitution of laF,CX in CH3X molecules probabIy occurs by an inversion mechanism.
