The information in the text is summarized as follows:
A visible-light-induced difluoroalkylation of N,N’-cyclicazomethine imine was successfully realized through a novel photoredox radical-radical cross-coupling reaction. This developed protocol exhibits high functional group tolerance and affords a variety of difluorinated 3-pyrazolidinone scaffolds. Extensive mechanistic investigations have been undertaken, well revealing the involvement of a reductive radical-radical coupling pathway. The experimental process involved the reaction of fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6Recommanded Product: 94928-86-6)
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. Recommanded Product: 94928-86-6
