Reactions involving nucleophilic aromatic substitutions (SNAr) are comparable (but faster) to the once of pyridine and are not covered in this group meeting. Multiple oxidations can be tricky... Nucleophilic reactions on PNO Aminations – not this way...

2,3-Dichloropyridine N -oxide as oxygen transfer reagent enables gold (I)-catalyzed oxidation of alkynes to 1,2-dicarbonyls in the absence of any acid additives and under mild conditions. The developed strategy is also effective for ynamides, alkynyl ethers/thioethers, and substrates bearing highly acid-sensitive groups.
