  Mild acetalisation of mono and dicarbonyl compounds catalysed by titanium tetrachloride. Facile synthesis of β-keto enol ethers

  摘要：

  The use of TiCl4, as a catalyst for the acetalisation, at room temperature, of carbonyl compounds is reported. Cyclic ketones and cyclic 1,4-diketones easily afford dimethyl acetals, but cyclic 1,3-diketones give beta -keto enol ethers. Additionally, aryl ketones and acyclic ketones failed to react. beta -keto aldehydes can be monoprotected either as beta -keto enol ethers or beta -keto dimethyl acetals depending on the reaction time and catalyst amount. Some mechanistic features are accounted for. (C) 2000 Elsevier Science Ltd. All rights reserved.

  The invention provides an actinically-crosslinkable linear polysiloxane copolymer. The actinically-crosslinkable polysiloxane copolymer can be used to prepare a silicone hdyrogel contact lens having a hydrophilic surface without post-curing surface treatment. The invention is also related to a silicone hydrogel contact lens obtained from a lens-forming material including an actinically-crosslinkable polysiloxane copolymer of the invention and to a method for making an actinically-crosslinkable polysiloxane copolymer of the invention. In addition, the invention provides a non-crosslinkable linear polysiloxane copolymer capable of being used as a internal wetting agent which can render the surface of a silicone hydrogel contact lens hydrophilic.
