α-Functionalized ketones can be conveniently prepared in one step by the reaction of ketones possessing α-methene with o-iodoxybenzoic acid (IBX) in the presence of potassiumiodide. Methyl aryl ketones produced bi-substituted products, whereas the others gave mono-substituted ones.

The oxidative coupling of carboxylic acids with liquid ketones and cyclic ethers has been accomplished in minutes using t-butylhydroperoxide in the presence of tetrabutylammonium iodide under microwave irradiation in the absence of a solvent. In addition to drastically shortening the reaction times, the use of microwaves resulted, in general, in yields equal to or higher than those obtained by conventional
