Tribromomelamine (TBM) can be used as a novel catalyst for the trimethylsilylation of alcohols and phenols with 1,1,1,3,3,3-hexamethyldisilazane (HMDS). A wide variety of hydroxyl groups were selectively protected in CH 2 Cl 2 /CH 3 CN under mild conditions.
三溴三聚氰胺 (TBM) 可用作醇和酚与 1,1,1,3,3,3-六甲基二硅氮烷 (HMDS) 的三甲基甲硅烷基化的新型催化剂。在温和条件下,多种羟基在 CH 2 Cl 2 /CH 3 CN 中被选择性保护。
