Abstract EN
The mass fragmentation pattern of azetidine-2-one 3(c-e) and azetidne-2,3-dione 5f,5g in each case the molecular ion peaks were observed corresponding to molecular weight of the coupled products .The base peaks were observed also for each compounds.
the mass fragment -lactam gave four ion in two directions, the first to give an olefin and isocyanate and the second to generate the original reactants that is ketene and phenyl .
mercapto-5- phenyl -4H-1,2,4-triazoles 2a-b.
gave tropylium Cation at m/z as well as heterocyclic moiety were observed in the spectrum The mass fragmentation pattern of in each case the molecular ion peaks were observed corresponding to molecular weight of the coupled products .The base peaks were observed also for each compounds
