Collisionally activated decomposition (CAD) mass spectra of the (1-) ions of 1-methyl ester-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 groups is the salient feature of all the CAD spectra.
