Part-IResults and Discussionneutral CO from the daughter ion (c) gives the fragment (d) and loses of methyl radicalgives fragment (g). Fragment (g) loses neutral CO molecule to give fragment (h). Thisfragment subsequently gives fragment (j) and (k) by the lose of propylene and ethyleneion, respectively. In some of the spectra, lose of H 2 S from the molecular ion has also beendetected to give the fragment (e), which further loses methyl radical to give fragment (f).Breaking of carbon/sulfur bond in the molecular ion and subsequent lose of oxygenradical gives two daughter ions (a) and (b). The fragmentation pattern of thesecompounds compliance with the assigned structure to the compounds (Scheme-25).110
