NaHSO4中心点SiO2被用作一种有效的多相催化剂，用于苄叉缩醛的形成和裂解。该催化剂与许多官能团或保护基团相容。在不同的溶剂体系下，苄叉缩醛的生成和裂解均顺利进行，产率高，化学选择性好。
NaHSO4 center dot SiO2 was used as an efficient heterogeneous catalyst for both the formation and the cleavage of benzylidene acetals. This catalyst is compatible with many functional or protective groups. Under different solvent systems, either the formation or the cleavage of benzylidene acetals was carried out smoothly in excellent yields and with good chemoselectivity.
