An atom- and step-economical, efficient and eco-friendly method for constructing naphthoselenazol-2-amines through a visible-light photocatalytic multi-component reaction under aqueous phase conditions is reported. This visible-light-induced reaction proceeded at room temperature under exogenous photosensitizer- and additive-free, neutral and mild conditions with low-cost and abundant elemental selenium as the selenium source, ambient air as the clean oxidant and pure water as the sole solvent.
