Chemically inert fluorinated organosilicon compounds for use as, e.g., lubricants are described corresponding to the formulae R14Si or R23Si(R3SiR42)zR23, where z is from 1 to 4, inclusive, at least three of the R1 radicals, at least two of the terminal R2 radicals, and preferably one of the non-terminal R2 radicals are derived from (a) monovalent alkyl-terminated fluorotelomers of chlorotrifluoroethylene or (b) monovalent alkyl-terminated fluorocotelomers of chlorotrifluoroethylene and either hexafluoropropene or mixtures of hexafluoropropene and tetrafluoroethylene, and R3 represents an alkenyl-terminated divalent fluorotelomer or cotelomer, and the value of z is from 1 to 4, inclusive.
