Abstract

The decomposing molecular cations derived from (substituted) 2โ€nitrothiobenzamides fragment by complex rearrangement reactions. When the alkyl substituents (R) attached to N are methyl, the major fragmentations are [M]^+^ห™ โ†’ [M๏ฃฟSO]^+ห™^ and [M๏ฃฟSO]^+ห™^ โ†’ [(M๏ฃฟSO)^+ห™^โ€“Rห™]^+^. This remains a basic pathway when R โฉพ Et, but other rearrangements are also observed. For example, when R=Et, additional competitive processes are [M]^+ห™^ โ†’ [M๏ฃฟHOห™]^+^ and [M]^+ห™^ โ†’ [M๏ฃฟC~2~H~4~O]^+^ห™.

## 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.
