The recent development of β‐cyclodextrin‐based catalysts system in Suzuki coupling reactions

Abstract

β‐Cyclodextrin has drawn significant attention as a special class of cyclic oligomers over the past few decades. They have been employed in many organic conversions as green alternative catalysts to perform satisfactorily in catalytic activity and modify the efficiency of organic reactions. Its availability, nontoxicity, low cost, renewability, and high performance in organic transformations are several benefits of cyclodextrins that have captured the interest of many research groups worldwide. In recent decades, great progress has been made in developing metal‐catalyzed coupling reactions to create carbon–carbon bonds. For the transition‐metal‐catalyzed cross‐coupling, using modified β‐cyclodextrin derivatives as catalysts is much more pleasant due to the obvious advantages such as valuable catalytic properties and the capability to create an inclusion complex with different metals. The particular purpose of this review is to summarize the application of β‐cyclodextrin‐based catalyst systems in Suzuki coupling reaction for the synthesis of biaryl compounds covering the years 2019–2023.
