  A metal-free protocol for the α-benzoxylation of ketones has been developed by using terminal aryl alkenes as an arylcarboxy surrogate. Moderate to good yields were attained for a variety of propiophenones and acetophenones by using tetra-n-butylammonium iodide (TBAI) as the catalyst and tert-butyl hydroperoxide (TBHP) as the oxidant under ambient reaction conditions.

  Abstract The 1,2-dibromoethane- and KI-mediated α-acyloxylation of ketones is reported in moderate to good yield without the use of transition metals and strong oxidants. Various acids are well tolerated with wide functional group compatibility. An 1,2-dibromoethane- and KI-catalysed reaction mechanism is proposed based on the results of control experiments.

  It′s the iodine: The intra‐ and intermolecular title reaction is catalyzed by an in situ generated ammonium (hypo)iodite species. Either H2O2 or tert‐butyl hydroperoxide (TBHP) can be used as an environmentally benign oxidant and a wide range of substrates react to give the corresponding α‐acyloxycarbonyl compounds in good to excellent yields.

  With tetrabutylammonium iodide (TBAI) as the catalyst and tert-butyl hydroperoxide (TBHP) as the oxidant, a simple metal-free protocol has been developed for the synthesis of α-acyloxycarbonyl compounds from carbonyl compounds and α-oxo carboxylic acids via decarboxylative coupling reaction.
