In the electron impact induced fragmentation of 2,3-disubstituted 5,6-dihydro-1,4-oxathiines, the cleavage of the heterocyclic ring proceeds through the retro Diels-Alder type of reaction. The further fragmentation of the resulting radical cation gives rise to substituted carbonyl or thiocarbonyl ca
## Abstract The electron impact‐induced fragmentations of 2,3‐dihydro‐1,5‐benzothiazepin‐4(5__H__)‐ones and some related compounds were investigated. On the basis of low‐ and high‐resolution measurements, metastable ion studies by means of mass‐analysed ion kinetic energy spectroscopy and collision
