New Mass Spectra Electron Impact Induced Skeletal Rearrangement of ZAmidobenzothiazoles

There has been a number of previous studies of the mass spectral fragmentation of benzothiazoles and their substituted derivatives.' However there are few reports about the substituted 2-amidobenzothiazoles. In this paper we report the mass spectra of ten new 2-amidobenzothiazoles. Their structural formulae are shown as : 0 NH-C-R No. 1 2 3 4 5 6 7 8 9 10 M R

## Abstract The decomposing molecular cations derived from (substituted) 2‐nitrothiobenzamides fragment by complex rearrangement reactions. When the alkyl substituents (R) attached to N are methyl, the major fragmentations are [M]^+^Λ™ β†’ [Mο£ΏSO]^+Λ™^ and [Mο£ΏSO]^+Λ™^ β†’ [(Mο£ΏSO)^+Λ™^–RΛ™]^+^. This remains a
