Various olefins can be hydrogenated quantitatively with neutral, flavin-derived catalysts in the presence of hydrazine under an under an athomspheric pressure of O2. A vitamin B2 derivative acts as a highly efficient and robust catalyst for the an environmentally benign process producing water and nitrogen gas as the only waste products.

Olefins can be hydrogenated by treatment with hydrazine in the presence of a 5-ethyl-3-methyllumiflavinium perchlorate catalyst under O2 atmosphere to give the corresponding hydrogenated products in excellent yields along with environmentally benign water and molecular nitrogen as the only waste products.
