The invention relates to a radical-initiated thiol-ene or thiol-yne “click” reaction that provides a simple and efficient route to diverse trialkoxysilanes. Trialkoxysilanes made in this way are obtained in quantitative to near-quantitative yields with high purity without any or minimal purification. A wide range of functional groups is tolerated in this approach, and even complex alkenes click with the silane precursors. The modular nature of these radical-based thiol-ene or thiol-yne “click” reactions allows a wide variety of pendant groups to be coupled to silane compounds that can then be coupled to a wide variety surfaces in order to modify their material properties. Consequently, such radical initiated thiol-ene and thiol-yne reactions provide facile and efficient methods for preparing an enormous number of surface-active functional trialkoxysilanes.
本发明涉及一种基于自由基引发的巯基-烯或巯基-炔“点击”反应,该反应提供了一种简单高效的途径来制备多样化的三烷氧基硅烷。以这种方式制备的三烷氧基硅烷可以在无需或最小程度净化的情况下以高纯度和量化至近量化产率获得。这种方法可以容忍多种功能基团,甚至复杂的烯烃也可以与硅烷前体进行“点击”反应。这种基于自由基的巯基-烯或巯基-炔“点击”反应的模块化特性允许将各种挂链基团耦合到硅烷化合物中,然后将其耦合到各种表面上以改变其材料性能。因此,这种基于自由基引发的巯基-烯或巯基-炔反应为制备大量表面活性功能三烷氧基硅烷提供了简便高效的方法。
