Abstract: The electron impact mass spectra (EIMS) and chemical ionization mass spectra (CIMS) of seven new N-alkyl-N'-ethoxycarbonylmethyl-N'-arylsulfonyl-O-ethyl phosphorodia-midoates are reported.The results show the EIMSand CIMSof this type compound all have many ion peaks produced through skeleton rearrangements.The difference of substituents has an effect on the mass spectra.P-Nbond cleavage is important mass spectra behaviour in EIMS.MH+ ions have higher relative intensity in CIMS case.There are many products from ion-molecular reaction.

Key words: EIMS, CIMS, Skeleton rearrangement, Substitution effect, Phosphorodiamidoates
