Abstract: The mass spectra of a new type of organophosphorus compounds O-ethyl-N-isopropylphos-phoro (thioureido) thioates have been studied using low and high resolution EIMS andB/E, B2/E linked scanning Lechniques. Attention was focused on P-N bond cleavage, whichinvolves simple fragmentations and rearrangement as well as loss of HS·, H2S. The effectsof substituents R″of thioureido on above reactions have been discussed as well.

Key words: B/E and B2/E linked scanning, High resolution accurate mass measurement, Rearrangement reaction, Phosphorothioate
