Abstract The first mercury-catalyzed synthesis of 1,2-diketones by alkyne oxidation has been developed. This inexpensive method extends the potential of mercury catalysis and allows the rapid construction of various 1,2-diketones and α-carbonyl amides in good yields with high functional group tolerance.

A novel copper-catalyzed N-oxide oxidation of N-sulfonyl ynamides is disclosed. This non-noble metal-catalyzed protocol enables facile and efficient access to valuable α-keto imides in generally good to excellent yields. Other notable features of this method include widespread availability of the substrates, compatibility with broad functional groups, a simple procedure, mild conditions, and in particular
