Intermolecular Electrochemical C(sp3)-H/N-H Cross-coupling of Xanthenes with N-alkoxyamides: Radical Pathway Mediated by Ferrocene as a Redox Catalyst

Efficient intermolecular dehydrogenative cross-coupling of N-alkyloxyamides with xanthenes is reported. The protocol is carried out in an undivided cell under constant current conditions employing simple, cheap and readily available ferrocene (Fc) as a redox catalyst. Cyclic voltammetry and control experiments disclosed that the dehydrogenative cross-coupling reaction may proceed via an amidyl radical.
