We present a metal-free method for α-acetoxyarone synthesis by self-intermolecular oxidative coupling of aryl ketones using I2−tert-butyl hydroperoxide (TBHP). Under the optimum conditions, various aryl ketones gave the corresponding products in moderate to excellent yields. A series of control experiments were performed; the results suggest the involvement of radical pathways. Multiple radical intermediates were generated in situ and the overall process involved several different reactions, which proceeded self-sequentially in a single reactor. A labeling experiment using 18O-labeled H2O confirmed that the oxygen in the product was derived from TBHP, not from H2O in the TBHP solvent.

An efficient synthesis of tert-butyl peroxides through TBAI-promoted acyloxylation–peroxidation of alkenes by using a carboxylic acid and tert-butyl hydroperoxide was developed. The synthetic utility of our method is enhanced by simple manipulations, easily available starting materials, and a wide substrate scope.

An efficient and environmentally benign procedure has been developed for the epoxidation of naphthoquinone derivatives by using tetrabutylammonium iodide as a catalyst and tert-butyl hydroperoxide as an oxidant in the presence of silicon dioxide. This protocol, which provides a facile base-free methodology for the synthesis of some new naphthoquinone-based epoxides, features mild reaction conditions, high yields, remarkably short reaction time, and broad substrate scope
