Grignard reagents to functionalized ketoxime-phosphine oxides and -phosphonates is described. Aziridines are used as intermediates for the regioselective synthesis of fluorine containing β-amino phosphine oxides and β-amino phosphonates. Amino phosphorus derivatives can also be obtained from ketoximes derived from phosphine oxides and phosphonates with sodium borohydride.
The reaction of perfluoroalkylated α,β-unsaturated phosphorates with saturated methanolic ammonia solution afforded 2-amino-2-perfluoroalkylethylphosphonates, and with benzylamine gave 2-benzylamino-2-perfluoroalkylethylphosphonates which upon hydrogenation gave 2-amino-2-perfluoroalkylethylphosphonates.
