✦ Synopsis

Collisionally activated decomposition (CAD) mass spectra of the [ M -C,F,CH,'Iions of 1-methyl ester-1 1pentafluorobenzyl ester-9,12,15-tris(trimethylsilyI) and 9,12,15-tris(ethyldimethylsilyl) ether derivatives of 11dehydrothromboxane B, are presented and discussed. The spectra are interpreted with the aid of those of a corresponding 3,3,4,4tetradeutero compound and of an analogous derivative of 1 ldehydrothromboxane B, . 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.
