The fragmentation of 1 is up to 10 20 times faster if it is present as radical ion and not as neutral compound. This acceleration has thermodynamic reasons, which surprisingly lead almost exclusively to a lowering of the energy of the transition state, even for weakly endergonic processes. The term (catio‐/anio) mesolytic is proposed for the fragmentations of radical ions.
