  Occlusion of Grubbs' Catalysts in Active Membranes of Polydimethylsiloxane:  Catalysis in Water and New Functional Group Selectivities

  摘要：

  The Grubbs' first and second generation catalysts were occluded into cross-linked slabs of polydimethylsiloxane with volumes from 1 mm3 to 1 cm3 by swelling the polymer with catalyst and methylene chloride. Methylene chloride was evaporated under vacuum to yield occluded catalysts where their solvent was polydimethylsiloxane. These occluded catalysts were reacted with alkenes dissolved in H2O or H2O/MeOH mixtures that diffused into the polydimethylsiloxane to react by ring-closing metathesis and cross metathesis. Control experiments revealed that the catalysts remained occluded and metathesis did not occur in the solvent. Occlusion of these catalysts allowed commercially available Grubbs' catalysts to be used with H2O as the solvent while isolating the H2O sensitive ruthenium methylidene from exposure to H2O. Functional group selective experiments were carried out where the polydimethylsiloxane was an "active" membrane to exclude salts. Polydimethylsiloxane is a hydrophobic polymer, so the deprotonated salt of diallylmalonic acid did not diffuse into it while a diallylether diffused into it and reacted by metathesis. Thus, by controlling the polarity of reagents their reactivity can be controlled owing to the properties of polydimethylsiloxane rather than those of the Grubbs' catalysts. Occlusion of catalysts in polydimethylsiloxane has been shown to add new selectivities to mature catalysts.

  The present invention relates to an organosiloxane compound suitable for the modification of silicone rubbers and synthetic resins, an organosiloxane compound useful as its intermediate, and a process for preparing them. The organosiloxane compound of the present invention can be represented by the general formula (IV) wherein j is an integer of 1 to 2000, R is an alkyl group having 1 to 4 carbon atoms, and R1 is a pentafluorophenyl group or a straight-chain or a branched fluoroalkyl group represented by the formula (II) wherein a is an integer of 3 to 18, and b is an integer of 0 to 2a.Furtheremore, the siloxane compound of the present invention may have one, two or three siloxane chains each having a substituent with a fluorine atom containing group at the terminal thereof. Each of molecules constituting the polysiloxane compound of the present invention has a terminal hydrosilyl group portion and a fluorine atom-containing terminal substituent portion therein. Since the reactive group of the hydrosilyl group is chemically bonded to the synthetic resins, the deterioration in characteristics with time can be hindered. The synthetic resins can be provided with the specific function of the fluoroalkyl group without impairing characteristics which the polysiloxane has.
