Vinylsilanes were directly prepared from the corresponding vinyl triflates under magnesium-promoted reductive conditions in THF with no transition metal catalyst, and gem-bis-silylated compounds were obtained in NMP. Investigation of the redox potential of starting materials and products suggested that reductive coupling reactions of vinyl triflates might be controlled by the reduction potential. A
直接从相应的三氟甲磺酸乙烯基制备乙烯基硅烷镁促进的还原条件下,在THF,没有过渡金属催化剂,和宝石-双-甲硅烷基化的NMP中得到的化合物。对起始原料和产物的氧化还原电势的研究表明,乙烯基三氟甲磺酸酯的还原偶联反应可能受还原电势控制。各种宝石-双-甲硅烷基化的化合物和3- silyladipic酸酯很容易在从以高收率乙烯基三氟甲磺酸酯只有两个步骤合成。
