Various olefins can be hydrogenated quantitatively with neutral flavin 2 catalysts in the presence of 1-2 equiv of hydrazine under 1 atm of O(2), Vitamin B(2) derivative 2g acts as a highly efficient and robust catalyst for the present environmentally benign process producing water and nitrogen gas as the only waste products.
Aerobic Reduction of Olefins by In Situ Generation of Diimide with Synthetic Flavin Catalysts
5‐bis(acylamino)pyridine 15 exhibit unprecedented catalytic activities, with the reduction of aromatic and hydroxy olefins proceeding significantly faster when a higher‐generation dendrimer is used as a host pair for the association catalysts. Contrasting retardation is observed upon similar treatment of non‐aromatic or non‐hydroxy olefins with the dendrimer catalysts. Control experiments and kinetic studies
