Synthesis and characterization of octakis(3,3,3-trifluoropropyldimethylsiloxy)cyclotetrasiloxane (I), octakis[tridecafluoro-2,2,5,5-tetramethyl-2,5-disilatridecanoxy]cyclotetrasiloxane (II) and octakis(7-pentafluorophenyl-2,2,5,5-tetramethyl-2,5-disilahep

Octakis(3,3,3-trifluoropropyldimethylsiloxy)cyclotetrasiloxane (I), octakis[tridecafluoro-2,2,5,5-tetramethyl-2,5-disilatridecanoxy]cyclotetrasiloxane (II), and octakis(7-pentafluorophenyl-2,2,5,5-tetramethyl-2,5-disilaheptanoxy)cyclotetrasiloxane (III) have been prepared and characterized. Reaction of octakis[chloro calcium oxy]cyclotetrasiloxane (Ca8Si4O12Cl8) with 3,3,3-trifluoroproyldimethylchlorosilane yields I, II, and III, on the other hand, have been prepared by platinum catalyzed hydrosilylation reactions of octakis(vinyldimethylsiloxy)cyclotetrasiloxane with tridecafluoro-1H,1H,2H,2H-octyldimethylsilane and 2-pentafluorophenyl-1H,1H,2H,2H-ethyldimethylsilane, respectively.
