Oxidovanadium(IV) sulfate, VIVOSO4, is shown to catalyze efficiently the amidation of the C-H bond of aldehydes by N-chloramine derivatives for the selective synthesis of amides. The catalytic process is driven by visible light irradiation at room temperature, and the reaction is carried out in ethyl acetate, a green and bio-based solvent. [...]

Ecological stoichiometry is essential for understanding the biogeochemical cycle in forest ecosystems. However, previous studies of ecological stoichiometry have rarely considered the impacts of forest origins, which could help explain why to date so much uncertainty has been reported on this subject.
