Methansulfonic acid/di-phosphorus pentoxide (4:1) was found to be an efficient reagent for one-pot synthesis of acylaryl methane sulfonates of phenolic esters via Friesrearrangement. This method is easy, rapid, and high-yielding reactions for the synthesis of acylaryl methane sulfonates.
To explore further the practical uses of highly active manganese (Mn*), a variety of alcohols were treated with Mn*, and the resulting complexes were coupled with acid chlorides and/or acetic anhydride in the absence of any extra catalyst. The subsequent reactions took place smoothly under mild conditions, providing the corresponding O-acylation products in good to excellent isolated yields.

Methanesulfonicacid/phosphorus oxychloride (MAPO) was found to be a new effecient reagent in the Fries rearrangement of phenolic esters. Fries rearrangement of phenolic esters in the presence of MAPO, gave acylaryl methane sulfonates as major products.
