β¦ Synopsis
1 ,l -Difluorodecamethyl-and 1 ,I ,4,4-tetrafluorooctamethylcyclohexasilane were synthesized by the reaction of LiF with the corresponding trifluoromethanesulfonic derivatives and were characterized by spectroscopic methods, mainly by modern N M R techniques. The stability of the fluorinated cyclosilanes decreases with an increase of fluorine substituents. This seems to be the reason for the instability of perfluorinated cyclosilanes.

THE substitution of hydrogen by fluorine transforms in some cases a metabolite into an anti-metabolite; in others, it produces a substance which can be incorporated by the cell instead of the %orma118 compound. In view
