Abstract

Sulfuryl fluoride activates the carbonyl groups of amides as nucleophiles while the activated hydroxyl groups of alcohols act as electrophiles. The amide C-N bonds could be easily cleaved to form the ester C-O bonds at room temperature without using transition metals. The reaction offers broad substrate scope and excellent functional group compatibility.
