Trimethylsilylation and methylation of 1 -hydroxybenzotriazole 3-oxide (1) proceed regioselectively and afford 1-trimethylsilyloxy- and 1-methoxybenzotriazole 3-oxides, respectively. The first compound easily undergoes fast hydrolysis and methanolysis, but does not react with nitroethane at 20 °C. A fast reversible 1,5-O,O-migration of the SiMe3 group is observed for this compound.
1-羟基苯并三唑 3-氧化物 (1) 的三甲基甲硅烷基化和甲基化发生区域选择性,分别得到 1-三甲基甲硅烷氧基和 1-甲氧基苯并三唑 3-氧化物。第一种化合物很容易进行快速水解和甲醇分解,但在 20 °C 下不与硝基乙烷反应。对于该化合物,观察到 SiMe3 基团的快速可逆 1,5-O,O-迁移。
