carboxylic acids were transformed into their trimethylsilyl esters with HMDS in a practically completely solvent-free process, while a catalytic amount of iodine was required in some cases. The process has several advantages over the known methods: untreated reactants, air atmosphere, mild and neutral conditions, no evolution of hydrogen halide, no need of an additional base, low amount of waste, completely
在几乎完全无溶剂的过程中,使用HMDS将多种结构不同的羧酸转化为三甲基甲硅烷基酯,而在某些情况下则需要催化量的碘。与已知方法相比,该方法具有多个优点:未处理的反应物,空气气氛,温和和中性条件,不产生卤化氢,不需要额外的碱,废物量少,完全无需色谱法,能源消耗低以及可操作简单。
