Notes:
The mass spectra of the compounds C12F8M2 (M = S, Se), (I), C12F8M (M = S, Se, Te), (II) and C12F8SX2 (X = Br, I), (III), have been measured. Results indicate that sulfur-carbon bonds are more stable under electron bombardment than either selenium-carbon or tellurium-carbon bonds. Numerous metastable-supported transitions are evident, which are incorporated into comprehensive fragmentation schemes for these compounds. Many metastable transitions, not previously reported, were observed for the fluorocarbon fragments and a fragmentation scheme is reported.The bromine and iodine-containing compounds behave remarkably like the heterocyclic systems, I and II, presumably due to initial loss of Br2 or I2 to form a ring system of type II.
