The reaction of perfluoroalkylated alpha,beta-unsaturated phosphonates
with saturated methanolic ammonia solution afforded 2-amino-2-perfluo
roalkylethylphosphonates, and with benzylamine gave 2-benzylamino-2-pe
rfluoroalkylethylphosphonates which upon hydrogenation gave 2-amino-2-
perfluoroalkylethylphosphonates.
