Silicondifluoride reacts with CF3I to give mainly CF3SiF2I. Other products are CF3SiF2SiF2I, SiF3SiF2I, SiF3SiF2SiF2I, SiF2ISiF2I and SiF2ISiF2SiF2I. The mass spectra and NMR spectra of these compounds are described and also the i.r. spectrum of CF3SiF2I is reported. A reaction mechanism which accounts for these products is proposed.

Reactions of SiF2 with halogens have been reinvestigated by both co-condensation and gas-phase methods. The co-condensation method yields a number of fluorohalogenosilanes including mono-, di-, and higher silane derivatives. These compounds contain SiF, SiF2, and SiF3 units. The reactivity towards SiF2 decreases from chlorine through bromine to iodine. While chlorine and bromine give rise to a number
