• 論文の詳細を見る

• The migratory aptitude of the aryl group in the unimolecular ion decomposition reaction of <I>p</I>-substituted diaryl sulfones has been examined. Both electron-donating and -withdrawing substituents showed to be capable of increasing the migratory aptitude. On the other hand, a kinetic treatment allowed a satisfactory Hammett correlation (ρ=0.3) on the total abundances of the fragment ions. The energy of the cleaved bond and the production stability were shown to be important factors in the effect of the substituent on the ion decomposition.
