PhI(OAc)2âBF3âOEt2 mediated domino synthesis of biologically important fluorenones, xanthones and phenanthridines has been developed. The reaction proceeds through imine activation, intramolecular CâC bond formation and β-elimination.
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
