A visible-light-promoted fluoroalkylation-thiolation of alkenes is described. A 4-tetrafluoropyridinylthio fragment serves as a photoredox-active group in the initiation step and undergoes a radical group transfer, which is important for the reaction efficiency. In the primary products, the pyridinylthio substituent may be further functionalized via radical processes or an aromatic substitution reaction. The experimental process involved the reaction of fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6Electric Literature of C33H24IrN3)
fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Electric Literature of C33H24IrN3
