Abstract
The mass spectra of R3MSC6F5 and R3MOC6F5 (R = CH3 or C6H5; M = Si, Ge, Sn) are reported and compared with the corresponding pentafluorophenyl derivatives. The sulfur and oxygen compounds show fewer rearrangements leading to the formation of metal fluorides than do simple C6F5 derivatives. The ions R3M+ are usually observed as the base peaks. Ions containing Sn—S appear more stable than Sn—O species, while the reverse seems true for silicon.Keywords
