An alternate route for the synthesis of hybrid mesoporous organosilica with crystal-like pore walls from allylorganosilane precursors

The bridged allylorganosilanes 1,4-bis(diallylethoxysilyl)benzene and 1,4-bis(triallylsilyl)benzene are presented as new precursors for the surfactant-assisted synthesis of ordered mesoporous organosilica with pore walls having crystal-like molecular-scal

Meerwein's reagent mediated, significantly enhanced nucleophilic fluorination on alkoxysilanes

We developed a new facile method to fluorosilanes from alkoxysilanes using Meerwein's reagent. Our protocol afforded fluorosilanes in excellent yields in various organic solvents including acetonitrile under mild reaction conditions at room temperature. We also proposed a reaction mechanism with the probable silyloxonium intermediates. Georg Thieme Verlag Stuttgart · New York.

Hybrid organic-inorganic adsorbents

The present invention relates generally to hybrid organic-inorganic adsorbents for decontamination of fluids. Bridged poysilsesquioxanes are a family of hybrid organic-inorganic materials prepared by sol-gel processing of monomers that contain a variable organic bridging group and two or more trifunctional silyl groups. Specifically, the present invention relates to dipropylenedisulfide-co-phenylene-bridged polysilsesquioxane compositions, methods of making dipropylenedisulfide-co-phenylene-bridged polysilsesquioxanes, and methods of use of dipropylenedisulfide-co-phenylene-bridged polysilsesquioxanes. The present invention discloses properties of dipropylenedisulfide-co-phenylene-bridged polysilsesquioxanes that include high ligand loading, increased surface area, and increased porosity. These properties make dipropylenedisulfide-co-phenylene-bridged polysilsesquioxanes excellent adsorbents for decontamination of fluids for use in environmental and industrial processes.
