A mild mannered reaction: An ideal addition of “inert” arylCHbonds to CN groups has been achieved in the absence of any additives and without any undesirable by‐products (see scheme). The reaction can be carried out under mild conditions without the requirement of special techniques. Cp*=pentamethylcyclopentadienyl.

A three-component synthesis of α-substituted N-sulfonyl amines from aryl aldehydes, primary sulfonamides, and (hetero)arenes is described. This transformation enables a straightforward and modular synthesis of highly substituted sulfonamide scaffolds in good yields. The direct functionalization of C(sp2)–H bonds via cobalt-catalyzed C–H-activation offers an appealing and atom-economical alternative
