Tetraphenylstibonium methoxide (1) is an effective reagent for the synthesis of oxiranes and oxetanes from the corresponding 1,2- and 1,3-halohydrins, respectively. As the reaction conditions are neutral, oxiranes bearing an ester moiety were obtained intact without undergoing solvolysis. In addition, oxetanes, whose preparation was not generally facile, were formed in good yields under mild conditions (60-80°C).
四苯基锑甲氧基化合物(1)是合成氧杂环烷烃和氧杂环丙烷的有效试剂,分别来自相应的1,2-和1,3-卤醇。由于反应条件为中性,含有酯基的氧杂环烷烃未经历溶解,得以完整获得。此外,在温和的条件下(60-80°C),氧杂环丙烷的制备虽然通常不容易,但也能得到良好的产率。
