Process for the preparation of partially hydrogenated derivatives of 2-nitro-1,1,1-trifluoroalkanes

A process for the preparation of 2-oximino- and 2-nitro-1,1,1-trifluoroalkanes consisting essentially of catalytically hydrogenating a 2-nitro-1,1-,1-trifluoroalkane of the formula ##STR2## in which R is selected from the group consisting of hydrogen, an alkyl radical having 1 to 15 C atoms, and a cycloalkyl radical having 5 to 8 C atoms, with a catalyst containing a metal selected from the group consisting of ruthenium, rhodium, palladium, platinum, cobalt and nickel, until a maximum of 2.2 moles of hydrogen per mole of 2-nitro-1,1,1-trifluoroalkane have reacted.
