and convenient procedure for the easy conversion of various α-hydroxyphosphonates to α-trimethylsilyloxyphosphonates under mild conditions with HMDS in the presence of a catalytic amount of magnesium triflate as a highly stable and a non-hygroscopic recyclable catalyst in neat conditions is described. In order to show the general applicability of this method, we have also applied this procedure successfully
在催化量的三氟甲磺酸镁作为高稳定性和非吸湿性可回收催化剂的条件下,使用HMDS在温和条件下将各种α-羟基膦酸酯轻松转化为α-三甲基甲硅烷氧基膦酸酯的广泛,适用性强,高产率且方便的方法。描述了整洁的条件。为了表明该方法的一般适用性,我们还成功地将该方法用于普通醇和酚的甲硅烷基化。
