The use of tert-butyl hydroperoxide (TBHP) as a terminal oxidant in the presence of catalytic amount of tetrabutylammonium iodide and imidazole enables a transition-metal-free synthesis of aryl esters in high yield starting from benzylic primary alcohols and aliphatic alcohols. These reactions are highly chemoselective and tolerate a wide range of substituents.
