[RuH2(PPh3)4]-catalyzed michael addition reaction of α-fluoronitroalkanes

摘要

The Michael addition reactions of α-fluoronitroalkanes with various electron-deficient olefins were realized by catalysis of low-valence ruthenium species through Csp3-H activation, providing a useful way to construct a fluorinated quaternary carbon center. The reactions were carried out under neutral conditions, affording the desired products in moderate to excellent yields.
