Photoinduced decarbonylative C-C bond formation with readily accessible aldehydes as alkyl sources is described. This protocol provides a sustainable alternative for the effective construction of diverse valuable 4-alkylated sulfonyl ketimines under metal- and photosensitizer-free conditions. Significantly, in this reaction, air serves green oxidant, cyclic sulfamidate imines play dual role substrate photocatalyst, thus affording concise reaction system C-H alkylation imines.
