Abstract
Dimethyl 2-oxopropylphosphonate and diethyl 2,2-diethoxyethylphosphonate react with electron-rich arenes such as phenol, anisole, 1,3-dimethoxybenzene, and 1-methylpyrrole in the presence of trifluoromethanesulfonic acid to afford β,β-diarylphosphonates in moderate to good yield. The minor products observed in some cases are β -aryl-α,β -unsaturated phosphonates.
