Mass spectral studies of nitroindole compoundsAuthor(s): Anjali Tiwari, Meenakshi Jain
5-Nitro-2-aryl-1H-indole-3-carboxaldehydes have been synthesized by new improved and green chemistry techniques. Final confirmation is achieved fromFast atomic bombardment (FAB)mass spectrawhich exhibitmolecular ion peak (M++1) of compounds corresponding to their molecular masses. The fragmentation pathways of 5-nitro-2-(4-bromophenyl)-1H-indole-3- carboxaldehyde and 5-nitro-2-(4-fluorophenyl)-1H-indole-3-carboxaldehyde have been discussed. These spectra show some preferential fragmentation pattern.
