    • Fluorinated alkenylamines of the Formula V ##STR1## wherein n represents 0, 1, 2 or 3; R.sub.1 represents hydrogen or C.sub.1 -C.sub.10 alkyl and Y represents (a), when n represents O, CH.sub.2 F, (b), when n represents 1, CH.sub.2 F or CHF.sub.2, or (c) when n represents 2 or 3, CH.sub.2 F, CHF.sub.2 or CF.sub.3 are novel process intermediates. They are obtained by hydrolysis and subsequent reduction of the corresponding alkenyl fluorinated methyl ketimine magnesium halides, which are novel compounds resulting from reaction of the corresponding alkenyl magnesium halides with the corresponding fluorinated acetonitriles. The fluorinated alkenylamines of Formula V are oxidized while the amino group is protected to provide, after removal of the amine protecting group, the corresponding fluorinated methyl aminoalkanoic acids which are useful pharmacological or anti-bacterial agents.
