Notes:
Mass and tandem mass Spectrometric results for N-allyl-N′-arylsulphonylthioureas,-isothioureas and -guanidines using the pneumatically assisted electrospray (ionspray) technique are presented. The mass Spectrometric experiments show dominant quasi-molecular peaks of the monomers and signals of dimers and, more weakly, fragments. Full mass spectra are available from amounts below 500 fmol, indicating a high sensitivity. By tandem mass spectrometry of the protonated molecular ions and their fragments (sequential dau ghter-ion scanning) and using the chlorine and bromine isotope patterns, the fragmentation pathways were elucidated.
