leads to the formation of both monosodiumoxyorganoalkoxysilanes (MSOAS) and several secondary products. Analysis of experimental evidence makes it possible to advance the mechanism behind this phenomenon and to define the optimum conditions for the preparation of pure MSOAS with high yields. Different MSOAS were synthesized and their basic physicochemical properties were studied. MSOAS are shown to
详细研究了有机烷氧基硅烷与氢氧化钠的反应。研究表明,该反应涉及多个阶段,并且涉及相当复杂的多步骤过程,这会导致形成单钠氧基有机烷氧基硅烷 (MSOAS) 和几种副产物。对实验证据的分析可以推进这种现象背后的机制,并确定以高产率制备纯 MSOAS 的最佳条件。合成了不同的MSOAS并研究了它们的基本理化性质。MSOAS 被证明构成具有化学独立官能团的多功能试剂,它们与三甲基氯硅烷的反应通过 ONa 基团选择性地进行,而它们与三乙基硅烷醇和高级醇的相互作用仅通过 OAlk 基团进行。发现并详细研究了 MSOAS 和有机烷氧基硅烷之间通过 ONa 和 OAlk 基团的交换相互作用。与 MSOAS 热降解开始相对应的温度估计等于 180-190°C。© 2006 Wiley Periodicals, Inc. 杂原子化学 17:514–541, 2006; 在线发表于 Wiley InterScience
