AbstractCollisionally activated decomposition (CAD) mass spectra of the [M – C6F5CH2⋅]− ions of 1‐methyl cster‐11‐pentafluorobenzyl ester‐9,12,15‐tris(trimethylsilyl) and 9,12,15‐tris(ethyldimethylsilyl) ether derivatives of 11‐dehydrothromboxane B2 are presented and discussed. The spectra are interpreted with the aid of those of a corresponding 3,3,4,4‐tetradeutero compound and of an analogous derivative of 11‐dehydrothromboxane B3. Proposed fragmentation pathways are based on internal consistency of data from all four compounds. The migration of a trimethylsilyl or an ethyldimethylsilyl group is the salient feature of all the CAD spectra.
