2,2,6,6-四甲基哌啶是一种位阻仲胺，用于制备金属-酰胺碱(metallo-amide bases)和选择性制备硅基取代的烯酮缩酮(silyl ketene acetals)。 应用： 2,2,6,6-四甲基哌啶可用作反应剂，用于： 通过烯丙基氯类的烯丙基胺化合成烯丙化叔胺。 以Oxone为氧化剂，通过氧化反应合成羟胺。 以碘为氧化剂，与杂环硫醇反应合成次磺酰胺化合物。 与CO2和苯基硅烷经N-甲基化反应合成N-甲基化胺。 与醛和炔通过三组分Mannich偶联反应合成炔丙胺化合物。 2,2,6,6-Tetramethylpiperidineis a hindered secondary amine that is used to prepare metallo-amide bases and selective generation of silylketene acetals. Application： 2,2,6,6-Tetramethylpiperidine can be used as a reactant to synthesize: Allylated tertiary amines via allylic amination of allylic chlorides. Hydroxylamines via oxidation in the presence of oxone as an oxidant. Sulfenamide compounds by reacting with heterocyclic thiols in the presence of iodine as an oxidant. N-methylated amines via N-methylation by reacting with CO2 and phenylsilane. Propargylamines via three-component Mannich coupling reaction with aldehydes and alkynes.
