Abstract
A series of O,O-diphenyl [substituted (2-selenomorpholin-4-yl-acetyl amino)] alkyl phosphonates were synthesized by the reactions of selenomorpholine with O,O-diphenyl 2-chloro- acetylamino alkyl phosphonates. The structures of all new compounds have been confirmed by 1 H NMR, 31 P NMR, IR spectroscopy, Mass spectroscopy and elemental analyses.
