An alternative, mild procedure for the cleavage of t-butyldimethyisilyl and triphenyisilyl ethers to alcohols is shown, which is based on an exchange reaction with trimethylsilyl triflate below 0 °C. t-Butyldiphenylsilyl groups are not removed under these conditions.
显示了另一种温和的裂解叔丁基二甲基甲硅烷基和三苯甲硅烷基醚为醇的方法,该程序基于与三氟甲磺酸三甲基甲硅烷基酯在低于0°C的交换反应。在这些条件下不除去叔丁基二苯基甲硅烷基。
