  Silsesquioxanes as synthetic platforms. II. Epoxy-functionalized inorganic-organic hybrid species

  摘要：

  The vinyl cubic polyhedral silsesquioxanes (vinylSiO(1.5))(8) and [(vinylMe(2)SiO)SiO1.5](8) were epoxidized using ten equivalents of m-chloroperoxybenzoic acid (m-CPBA) per cube. The [(vinylMe(2)SiO)SiO1.5](8) compound converts, quantitatively, to the octaepoxide, [(epoxyMe(2)SiO)SiO1.5](8) as demonstrated by H-1, C-13, and Si-29 solution NMR, chemical and mass spectral analysis. The (vinylSiO(1.5))(8) cube was likewise fully epoxidized as determined by NMR; however, efforts to isolate it always led to intractable gels. Partial epoxidation was achieved using only three equivalents of m-CPBA. The partially epoxidized compound, when characterized by CI mass spectra, chemical analysis and NMR, was shown to have an average of two epoxy groups per cube. Both polyepoxides readily polymerized in the presence of Lewis acid catalysts or on reaction with simple amines, which suggests their potential as coupling agents in the synthesis of novel inorganic-organic hybrids.

  Highly effective functionalization of monovinylsiloxy heptaisobutylsilsesquioxane and octavinylspherosilicate of the formula (ViMe2SiO)(iBu)7Si8O12 (1) and (ViMe2SiO)8Si8O12 (2), respectively, with a variety of olefins, by using a Ru(H)(Cl)(CO)(PCy3)2-catalyzed silylative coupling procedure is reported. The cross-metathesis reaction catalyzed by a ruthenium–carbene complex does not proceed for this

  使用 Ru(H)(Cl)(CO) 分别用各种烯烃高效官能化单乙烯基甲硅烷氧基七异丁基倍半硅氧烷和八乙烯基球硅酸盐 (ViMe2SiO)(iBu)7Si8O12 (1) 和 (ViMe2SiO)8Si8O12 (2) )(PCy3)2-催化的甲硅烷基化偶联过程被报道。由钌-卡宾配合物催化的交叉复分解反应不会在该系统中进行。虽然 1 和 2 与苯乙烯的反应发生高度立体选择性和区域选择性，但与 1-己烯的相应反应产生异构体的混合物。然而，发现用乙烯基杂原子取代的 (N、O、Si) 衍生物对 1 和 2 进行官能化对于合成具有 β-杂原子乙烯基官能团的球硅酸盐非常有效 (© Wiley-VCH Verlag GmbH & Co.

  Octa(vinyl)-POSS or octa(vinyldimethylsilyloxy)-POSS reacts with perfluoroalkyl thiol in the presence of 2,2′-azobisisobutyronitrile to afford perfluoroalkylthioether substituted POSS compounds in high yields. 29Si NMR and MALDI-TOF mass spectroscopic analyses indicate that the eight perfluoroalkylthioether chains are attached to the POSS core structure. Studies on poly(methyl methacrylate) (PMMA) blends with 5 wt% fluorinated POSS (fluoroPOSS) reveal that the POSS molecules considerably enhance the hydrophobicity of polymer blend surfaces as evidenced by significant increases in water contact angles from 71° for pure PMMA to 114–124° for fluoroPOSS-blends, making this type of fluoroPOSS a promising new class of highly hydrophobic hybrid materials.

  八（乙烯基）-POSS 或八（乙烯基二甲基硅氧基）-POSS 与全氟烷基硫醇在 2,2′-偶氮二异丁腈的存在下发生反应，生成全氟烷基硫醚取代的 POSS 化合物，产量很高。29Si NMR 和 MALDI-TOF 质谱分析表明，八条全氟烷基硫醚链附着在 POSS 核心结构上。对含有 5 wt% 氟化 POSS（fluoroPOSS）的聚甲基丙烯酸甲酯（PMMA）共混物的研究表明，POSS 分子大大增强了聚合物共混物表面的疏水性，具体表现为水接触角从纯 PMMA 的 71° 显著增加到氟 POSS 共混物的 114-124°，从而使这类氟 POSS 成为一种很有前途的新型高疏水性杂化材料。
