Abstract

A chemo-divergent Friedel–Crafts alkylation and Friedel–Crafts acylation of arenes with α-diazo ketones has been developed. In this reaction, Cu(OTf)₂ catalyzed the Friedel–Crafts alkylation via Cu-carbene intermediate, while hexafluoroisopropanol (HFIP) promoted the Friedel–Crafts acylation via the ketene intermediate. This protocol provides a controllable aromatic C(sp2).H bond functionalization of arenes by tuning the reaction conditions.
