Electricity-Promoted Friedel–Crafts Acylation of Biarylcarboxylic Acids

An electricity-promoted method for Friedel–Crafts acylation of biarylcarboxylic acids is described in this research. Various fluorenones can be accessed in up to 99% yields. During the acylation, electricity plays an essential role, which might motivate the chemical equilibrium by consuming the generated TFA. This study is predicted to provide an avenue to realize Friedel–Crafts acylation in a more environmentally friendly process.
