Epoxide ring opening is a frequently required transformation in Organic Synthesis. In this paper we describe the application of NbCl5 for this purpose using three different substrates. Chlorohydrins, 1,2-diols, products containing solvent residues as well as rearrangement products are obtained, depending on both the substrate structure and reaction conditions. Rationalizations to account for some of
环氧化物开环是有机合成中经常需要的转化。在本文中,我们使用三种不同的基材描述了 NbCl5 为此目的的应用。获得氯醇、1,2-二醇、含有溶剂残留物的产物以及重排产物,这取决于底物结构和反应条件。建议对某些结果进行合理化解释。
