有机硅令人印象深刻的表面活性可以通过掺入亲水性有机官能团和聚合物来增强。这类化合物的传统途径通常涉及铂催化的硅氢化反应，与某些官能团不相容。B(C(6)F(5))(3)催化氢硅烷与烷氧基硅烷的缩合为制备明确的有机硅结构提供了新的机会。我们在这里证明，醇转化为硅醚与烷氧硅烷转化为二硅氧烷无生产竞争。相比之下，许多结构复杂的烷基卤化物和低聚乙烯基化合物可以很容易地以高收率制备。热3+2-环加成和巯基点击反应将这些化合物转化为表面活性物质。
The impressive surface activity of silicones can be enhanced by the incorporation of hydrophilic organic functional groups and polymers. Traditional routes to such compounds, which typically involve platinum-catalyzed hydrosilylation, suffer from incompatibility with certain functional groups. B(C(6)F(5))(3)-catalyzed condensation of hydrosilanes with alkoxysilanes offers new opportunities to prepare explicit silicone structures. We demonstrate here that conversion of alcohols to silyl ethers competes unproductively with alkoxysilane conversion to disiloxanes. By contrast, a wide range of structurally complex alkyl halide and oligovinyl compounds can be readily made in high yield. Thermal 3+2-cycloadditions and thiol-ene click reactions are used to convert these compounds into surface active materials.
