官能团的保护和脱保护是诸多多步有机化学反应必须涉及的．文章报道了在温和条件下，磺酸功能化的介孔材料（SBA‐15—SO3 H ）以及硅胶负载硫酸（SSA ）均是有效的叔丁基二甲基硅基醚保护基团的脱保护催化剂．SBA‐15—SO3 H的循环使用效果优于SSA ，而SSA的催化活性高于SBA‐15—SO3 H ．

Protection/deprotection of functional groups are widely used for multistep organic reactions .This paper indicates that under mild conditions ,sulfonic acid‐functionalized mesoporous (SBA‐15—SO3 H) and silica sulfuric acid (SSA) are used as efficient catalysts to the deprotection of tert‐butyldimethylsilyl (TBDMS) ethers . Particularly ,the recycling usage effect of SBA‐15—SO3 H is better than SSA ,while the catalytic activity of SBA‐15—SO3 H is less than SSA .
