The study describes the synthesis of disiloxanes, R₃SiOSiR₃, tetraorganodisiloxanes-1,3-diols, (RR¹SiOH)₂O, and silanol, t-Bu₂Si(H)OH, by AuNP-catalyzed hydrolytic oxidation of Si–H bond(s) in organosilanes. The method relies upon the en-route formation of an oil-in-water microemulsion that is dispersed in the continuous water phase and stabilized by amphiphilic AuNPs. The reaction of (MePhSiOH)₂O with (HMe₂Si)₂NH proceeds via O-silylation of silanol groups to afford an Si–H-terminated chain with the liberation of NH₃ as the byproduct. The application of this approach provides a viable synthetic solution to organosilica colloidal structures using primary organosilanes, RSiH₃ (R = Ph, n-hexyl) as substrates.

有机硅烷作为低聚硅氧烷和苯基二氧化硅球的合成前体

该研究描述了通过 AuNP 催化水解氧化 Si- 来合成二硅氧烷 R ₃ SiOSiR ₃、四有机二硅氧烷-1,3-二醇 (RR ¹ SiOH) ₂ O 和硅烷醇t -Bu ₂ Si(H)OH有机硅烷中的 H 键。该方法依赖于水包油微乳液的形成，该微乳液分散在连续水相中并由两亲性 AuNP 稳定。 (MePhSiOH) ₂ O与(HMe ₂ Si) ₂ NH的反应通过硅烷醇基团的O-甲硅烷基化进行，得到Si-H封端的链，并释放副产物NH ₃ 。该方法的应用为使用初级有机硅烷RSiH ₃ (R= Ph, n -Hexyl) 作为底物的有机二氧化硅胶体结构提供了可行的合成解决方案。
