Outcomes of Fragmentation Reactions

The fragmentation reaction of a radical ion produces a radical and a diamagnetic ion. The reaction constitutes a convenient and rapid method of generation of these intermediates [109], The products derived from these intermediates and the direct observation method indicate that the electron apportionment to the fragments follows the thermodynamic prediction, i.e. the most stable ion-radical pair is formed. [Pg.26]

The reverse reaction, the radical-ion coupling, is expected to have low activation energy if the cleavage reaction itself is endergonic (see above). The many known examples of SRN1 reactions [110] attest to the facility of that process. Indeed, in several cases the radical-anion coupling was shown to be diffusion limited [111]. Thus, for the purpose of kinetic analysis the reversibility of cleavage cannot be dismissed a priori. In several systems where the possibility of reversibility has been explicitly tested [29, 99, 102, 106] none was found. [Pg.26]
