Herein, a copper/TBHP catalyst system for the α-C-H acyloxylation of carbonyl compounds is developed using terminal alkynes as the acyloxy source. A variety of carbonyl compounds and terminal alkynes are tolerated in this reaction. In addition, its possible mechanism is proposed.

An efficient oxidative approach was developed for the α-benzoyloxylation of ketones using tert-butyl hydroperoxide (TBHP). This process provided facile access to a wide range of α-benzoyloxy ketones in good to excellent yields via the direct oxidative α-benzoyloxylation of a structurally diverse series of ketones using simple arylmethane compounds.

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. An efficient synthesis for the α-benzoxylation of aryl ketones has been developed by using terminal aryl alkenes as the arylcarboxy surrogate. The products were obtained in moderate to good yields for a broad scope of substrates. Tetra-n-butylammonium iodide (TBAI) and tert-butyl hydroperoxide (TBHP) were employed as the catalyst and oxidant, respectively.
