α-oxygenation of tertiary amines to the corresponding amidesusing oxygen as an oxidant. This visible-light-mediated oxygenation reaction exhibited excellent substrates scope undermildreactionconditions and generated water as the only byproduct. The synthetic utility of this approach has been demonstrated by applying onto drug molecules. At the end, detailed mechanistic reactions clearly showed the role
first catalytic process has been developed for the direct synthesis of amides from readily available petroleum by‐products (methylarenes) and amines using an iron catalyst. In this new catalytic reaction, the methylgroup of the methylarene is oxidized to the corresponding aldehyde through non‐directed CHoxidation followed by its oxidative amidation with N‐chloroamine, yielding the carboxylic amide
