Abstract
A hybrid catalysis that comprises an acridinium photoredox catalyst, a thiophosphate organocatalyst, and a nickel catalyst-enabled acceptorless dehydrogenation of hydrocarbons is reported. The cationic nickel complex played a critical role in the reactivity. This is the first example of acceptorless dehydrogenation of hydrocarbons by base metal catalysis under mild reaction conditions of visible light irradiation at room temperature.
摘要
报道了一种杂化催化体系，该体系包含吖啶光氧化还原催化剂、硫代磷酸有机催化剂和镍催化剂，可实现烃类的无受体脱氢反应。阳离子镍配合物在反应性中起着关键作用。这是首例在可见光照射、室温的温和反应条件下，通过廉价金属催化实现的烃类无受体脱氢反应。
