Herein, a hexafluoroisopropanol (HFIP)-promoted Wolff rearrangement reaction was developed, delivering various alpha,alpha-disubstituted carboxylic acid derivatives in good to excellent yields. In this reaction, alpha-diazoketone could be activated using HFIP under mild conditions via hydrogen bonding between hydroxyl and carbonyl groups.
