Keywords Acid–base bifunctional catalyst · Hierarchical zeolite · Tandem reaction · Deacetalization–Knoevenagel condensation 1 Introduction In recent years researchers have paid great attention to one- pot, multi-step reactions due to higher efficiency, reduction in the synthesis steps such as isolation of intermediates, purification, lower cost and decrease in waste [1 –3]. For Electronic supplementary material The online version of this article (https ://doi.org/10.1007/s1056 2-018-2301-z) contains this purpose, design and synthesis of catalysts that contain supplementary material, which is available to authorized users. two or three kinds of active sites are required. Particularly, acid–base bifunctional catalysts, which have the ability * Roozbeh Javad Kalbasi to interact with both nucleophiles and electrophiles, have email@example.com attracted great attention.
