Oxidation of alkynyl ethers and -amines with iodosylbenzene in presence of Rucatalysts affords a-keto esters and a-keto amides in 44-84% yield. These conversions can also be effected with RuO,. Oxidations based on iodosylbenzene are of current interest in connection with model studies for peroxidase

Abstract
Disubstituted acetylenes are oxidized with PhIO in presence of Ru‐catalysts to afford α‐diketones in 65–85% yield. Under the same conditions terminal acetylenes are cleaved to carboxylic acids.
