The mass spectra of five aryl (I to V) and four alkylsulfonylthioureas (VI to IX) have been recorded and mechanistic rationalizations are suggested for their principal fragmentation processes. The aryl analogs exhibited peaks in their mass spectra corresponding to skeletal rearrangements with elimin
