expanding the variety of catalytic methods for siloxane bond formation is explored. Alkoxysilanes react with methylallylsilanes in the presence of scandium(III) trifluoromethanesulfonate to yield disiloxanes and isobutene. The reaction proceeds through one-pot hydrolysis/O-silylation of alkoxysilanes with allylsilanes (via silanol intermediates) under mild conditions. Unsaturated siloxane products are used
探索了扩大硅氧烷键形成催化方法种类的潜力。在三氟甲磺酸钪 (III) 存在下,烷氧基硅烷与甲基烯丙基硅烷反应生成二硅氧烷和异丁烯。该反应通过烷氧基硅烷与烯丙基硅烷(通过硅烷醇中间体)在温和条件下的一锅水解/O-甲硅烷基化进行。不饱和硅氧烷产物用作通过催化氢化硅烷化反应进一步官能化的底物。
