                                    1,1,3,3-Tetramethyldisiloxane is decomposed by organyltrifluoro- and diorganyl-difluorosilanes already at 20-degrees-C in the presence of catalysts with formation of hitherto unknown 1,1-dimethyl-3,3-diorganyl-3-fluoro- and 1,1-dimethyl-3-organyl-3,3-difluorodisiloxanes of general formula R4-nSiFn-1OSiH(CH3)2 (n = 2-3) in yields of 50-70%.  On storing these decomposition products easily disproportionate in various directions, in which their propensity to disproportionation is determined by the nature of the substituents at the silicon atoms and the number of fluorine atoms in the molecule.
