Web20 mei 2016 · A plausible mechanism starts from 4b +· that results in J4 +· by inductive cleavage, followed by a neutral loss of isoprene to K4 +·. The α-cleavage of J4 +· would yield a primary radical, but this can immediately be stabilised if the α-cleavage is coupled with a hydrogen rearrangement to generate the conjugated radical cation K4 +·.
Fragmentation is a type of chemical dissociation, in which the removal of the electron from the molecule results in ionization. Removal of electrons from either sigma bond, pi bond or nonbonding orbitals causes the ionization. This can take place by a process of homolytic cleavage or homolysis or heterolytic cleavage or heterolysis of the bond.
