The Michael addition reactions of fluorinated nitro compounds with electron deficient olefins to give γ‐fluoro‐γ‐nitro‐esters, nitriles and ketones which bear a fluorinated quaternary carbon center were reported. The reactions were promoted by TMG, affording the desired adducts in acceptable to good yields.

The Michael addition reactions of alpha-fluoronitroalkanes with various electron-deficient olefins were realized by catalysis of low-valence ruthenium species through C-sp3-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.
