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

摘要

Partially hydrogenated derivatives of 2-nitro-1,1,1-trifluoroalkanes, in particular 2-oximino- and 2-hydroxylamino-1,1,1-trifluoroalkanes, are prepared by catalytically hydrogenating 2-nitro-1,1,1-trifluoroalkanes until a maximum of 2.2 moles of hydrogen per mole of 2-nitro-1,1,1-trifluoroalkane have reacted.
