Mass spectra of eight new 1,2,3,5‐polysubstituted pyrroles were studied by methods of electron impact, mass‐analysed ion kinetic energy and high‐resolution data. It has been found that five‐membered or six‐membered cyclic ions were formed and other rearrangement ions were observed in the mass spectra.
