Abstract

Catalytic amount of ytterbium(III) triflate [Yb(OTf) 3 ] has been used to catalyze Friedel–Crafts acylation and demethylation of aryl??methyl ethers in one??step reaction to produce hydroxyacylphenones with moderate yields under mild conditions. ... Catalytic amount of ytterbium(III) triflate
