Hypervalent iodine(III)-mediated decarboxylative acetoxylation at tertiary and benzylic carbon centers.

The decarboxylative acetoxylation of carboxylic acids using a combination of PhI(OAc) and I in a CHCl/AcOH mixed solvent is reported. The reaction was successfully applied to two types of carboxylic acids containing an α-quaternary and a benzylic carbon center under mild reaction conditions. The resulting acetates were readily converted into the corresponding alcohols by hydrolysis.
