The cocondensation reaction of S1F2 with B2H6 at a -196C surface gives a product which, by low-temperature evaporation in vacuo, yields nonvolatiles and diborane derivatives of the 1,1-fluorosilylated type, possibly of the heterocyclic class 1,1-Sif2nB2H4. These decompose very easily at low temperatures possibly autocatalytically to form nonvolatiles and polyfluoropolysilanes such products also come from the original cocondensation reaction. They include the known compounds SiF4, HSiF3, SiF32O, Si2F6, HSi2F5, and Si3F8, and the new compounds H3SiSiF3, H2SiSiF32, probably HSiSiF33 and SiSiF34 neither very stable, a somewhat unstable HSiF22SiF3, and other volatiles which are more difficult to identify.
