biologically active molecules and functional materials. Presented herein is a facile synthetic method for the construction of ketones via Ni-catalyzed cross coupling of epoxides with aryltriflates. A range of easily accessible epoxides can be highly regioselectively converted to the corresponding aryl ketones with good yields in a redox neutral fashion.
Electrochemical activation of trialkylstannylmethyl group as an electroauxiliary for carbenium ion generation enables the intramolecular Friedel–Crafts alkylation. Electrochemical activation of stannylmethyl group forms carbenium ion which can be trapped by intramolecular (het)aromatic nucleophiles for the formation of new 6-membered cycles.
