CH activation : A Rh III ‐catalyzed direct aldehyde CH amidation has been achieved with sulfonyl, aryl, and alkyl azides as the amine sources, and release of N 2 as the only byproduct (see scheme). More importantly, this catalytic reaction proceeds in the absence of external oxidants or additives, under mild conditions, at neutral pH under air. This reaction represents a new avenue for practical intermolecular CN bond formation by aldehyde CH bond activation. Cp*=1,2,3,4,5‐Pentamethylcyclopentadiene
