    • Diazonium salts have been demonstrated to be suitable precursors of triplet phenyl cation when appropriate triplet sensitizers (e.g. xanthone) are used, because direct irradiation may lead to singlet rather than triplet aryl cations. The singlet cation add to the solvent. See: S. Milanesi, M. Fagnoni and A. Albini, Chem. Commun., 2003, 216.

    • A protic medium was a must in the case of fluorinated 1b, similar to that which was observed in the case of 4-fluoroaniline, where the photoheterolytic path is exothermic only thanks to the formation of the H-F bond.

    • Indeed, the less nucleophilic benzene (N < -4.47) did not trap the 4-methoxyphenyl cation in MeCN or AcOEt, while with 2,3-dimethyl-2-butene (N = -1.0) arylation occurred efficiently (ca. 70% yield),see ref. 6a
