The reaction of α-halo ketones (α-iodocycloalkanones, α-bromocycloalkanones, α-iodo-β-alkoxy esters, and α-iodoacyclicketones) with irradiation under a high-pressure mercury lamp gave the corresponding α-hydroxyketones in good yields. For α-bromoketones, it was found that α-hydroxylation does not occur. However, α-bromoketones were converted into α-hydroxyketones in the presence of KI. In the case of α,α′-diiodo ketones, α,α′-dihydroxyketones, which up to now have scarcely been reported, were obtained. This reaction affords a new, clean and convenient synthetic method for α-hydroxy- and α,α′- dihydroxyketones.

Oxidation of olefins has been examined with the following three types of reagents; (i) (C6H5Se)2-Br2-(Bu3Sn)2O, (ii) (C6H5Se)2-t-BuOOH, and (iii) (C6H5Se)2-(C6H5SeO)20, and the corresponding α-phenylseleno carbonyl compounds have been obtained directly from the olefins.
