An efficient ligand-free Fe-catalyzed oxidative Ugi-type reaction toward the assembly of α-amino amides and short peptides is described. The reaction proceeds through the α-C(sp3)–H oxidation of N,N-dimethylanilines and further nucleophilic attack of the resulting iminium species by isocyanides. Additive screening showed that judicious choice of the carboxylic acid could lead to the formation of α-amino
harness aromatic isocyanides as visible-light photocatalysts in the α-amino C(sp3)–H functionalization is herein presented. Actually, the three-component cross-dehydrogenative coupling of aromatic tertiary amines with isocyanides and water leads to amide products under very mild conditions in high yields and with a good substrate scope. While the reaction with aromatic isocyanides proceeds upon direct

Due to their tunable porous structure and photoelectric properties, conjugatedmicroporouspolymers (CMPs) have provided a new platform for visible-light driven photocatalysis. Some synthetic methods like Sonogashira, Suzuki, oxidative coupling and trimerization reactions have been commonly employed to synthesize photocatalytically active CMPs, but the copper promoted azide–alkyne click reaction is
