Metal-free oxidation of ynamides is described, employing pyridine-N-oxides as oxidants under molecular iodine catalysis. In stark contrast to Br?nsted acid catalysis, iodophilic activation of ynamides diverts the reaction manifold into a dioxygenation pathway. This oxidation is very rapid at room temperature with only 2.5 mol % I2. Furthermore, this protocol could be extended to nonactivated alkynes, such as diarylacetylenes, to deliver various benzil derivatives.

A novel oxygenative cross dehydrogenative coupling of methyl ketones with para-C-H of primary anilines under a copper/oxygen catalytic system is described. This methodology features advantages including readily available starting materials, green oxidant, and broad functional group tolerance.
