A preferred method of the invention includes the reaction of nucleophilic compounds containing Si, F, N or O atoms, or combinations thereof, or latent moieties in the form of unsaturated or hydroxylated functional groups, with ethylenically unsaturated glycerol carbonate derivatives. The compounds and hydrogel polymers are useful for the preparation of contact lenses.

参考标题:Synthesis, Crystal And Molecular Structure Of N,N-Dimethyl-3-[tris(Trimethylsiloxanyl)Silyl]Pyrrolinium Chloride 作者:R. Rudert,G. Schmaucks |发布日期:1994.7 摘要:The Synthesis Of N,N-Dimethyl-3-[tris(Trimethylsiloxanyl)Silyl]Pyrrolinium Chloride Was Carried Out By Hydrosilylation Of 1,4-Dichlorobut-2-Yne With Tris(Trimethylsiloxanyl)Silane Followed By The Reaction Of The Product With Dimethylamine. The Structure Of The Crystalline White Solid Was Determined By An X-Ray Diffraction Study. The Siosi Angles Range From 145.8(3)° To 161.4(4)°. The Molecules Are
