Abstract

Cu(BTC) (BTC: 1,3,5-benzenetricarboxylate) as a heterogeneous catalyst in the presence of cesium carbonate as a base is reported for the borylation of α,β-conjugated enones by bis(pinacolato)diboron (Bpin). According to the hot-filtration test, Cu(BTC) is acting as a heterogeneous catalyst. Further, Cu(BTC) exhibits a wide substrate scope and can be reused in consecutive runs, maintaining a crystal structure as evidenced by powder X-ray diffraction (XRD). A suitable mechanism is also proposed for this transformation using Cu(BTC) as catalyst.

摘要

据报道，在碳酸铯作为碱的存在下，Cu(BTC)（BTC：1,3,5-苯三甲酸酯）作为非均相催化剂用于双(频哪醇合)二硼(Bpin)对α,β-共轭烯酮的硼化反应。根据热过滤试验，Cu(BTC)作为非均相催化剂起作用。此外，Cu(BTC)具有广泛的底物范围，并且可以在连续反应中重复使用，粉末X射线衍射(XRD)证明其保持晶体结构。还提出了一种以Cu(BTC)为催化剂进行这种转化的合适机理。
