by the irreversible loss of N2. Heinrich has provided evidence
that processes such as these can be facile especially with the
electron transfer from electron-rich tertiary benzylic radicals to
electron-poor diazonium ions.13 Ongoing work in our
laboratory will distinguish between closed catalytic cycles and
chain processes.
In summary, we have developed a mild, visible-light-
promoted remote Csp3−H functionalization of ortho-diazo-
niaphenyl alkyl sulfones. Key mechanistic steps in these
processes include intramolecular HAT and polar crossover by
single-electron oxidation of radicals to carbenium ions. We have
developed remote hydroxylations, etherifications, amidations,
and C−C bond formations using this strategy. A broader range
of transformations than those observed with Tzo sulfonates and
sulfonamides can be effected using ortho-diazoniaphenyl alkyl
sulfones. In addition, low loadings of relatively inexpensive
Ru(bpy)3Cl2 and the necessity of visible-light irradiation
distinguish the current methods from our previous report.
