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.

A series of 6-substituted ω-bromo-2-naphthyl ketones and 6-substituted 2-naphthacyl esters have been synthesized by greener synthetic method using fly-ash:water catalyzed aqueous phase reaction. These ketones and esters have been characterized by their physical constants, GC-MS, IR and NMR spectral data. These compounds exist as two rotomers and the carbonyl frequencies of these rotomers have been assigned and correlated with Hammett substituent constants, F, R and Swain-Lupton's parameters. The antioxidant activities of the synthesized esters have been evaluated.
