A Cu2O-catalyzed aerobic oxidative decarboxylative ammoxidation of phenylacetic acids and α-hydroxyphenylacetic acids enables the synthesis of various primary benzamides in good yields. This one-pot domino protocol combines decarboxylation, dioxygen activation, oxidative C-H bond functionalization, and amidation reactions.
