Abstract

We report a catalytic hydroarylation method to convert phenols to dihydrocoumarins in hexafluoroisopropanol (HFIP) using acid generated from sub‐stoichiometric amounts of acetyl chloride as catalyst. Attractive elements include easy set‐up and isolation, and applicability to a range of phenols including natural product substrates.
