Abstract
The interpretation of the electron impact mass spectra of O-(3-oxo 2-p henyl 2H-pyridazine-6 yl) diethylphosphinothioate (I), O-(3-oxo 2-phen yl 2H-pyridazine-6 yl) dipropylphosphinothioate (II), O-(3-oxo 2-pheny l 2H-pyridazine-6 yl) diphenylphosphionothioate (III), O-(3-oxo 2-phen yl 2H-pyridazine-6 yl) O,O-diphenyl phosphorothioate (IV), and 2-O-(3- oxo 2-phenyl 2H-pyridazine-6 yl) 2-thiono 5,5-dimetyl 1,3,2-dioxaphosp horinan (V) is presented. Elucidation of the fragmentation pathways wa s aided by metastable transitions of all the compounds and by exact ma ss measurements on compounds (II) and (V).
