synthetic route was developed for the decomplexation of F-BODIPYs (fluorine-substituted boron–dipyrromethenes) to afford dipyrrins in high yields. This was achieved by treating the F-BODIPYs with different Lewis acids such as ZrCl4, TiCl4, AlCl3, Sc(OTf)3, or SnCl4 in CH3CN/CH3OH under refluxing conditions. This synthetic strategy was efficient for different types of F-BODIPYs such as meso-aryl-substituted
开发了一种简单的合成路线,用于对 F-BODIPY(氟取代的硼-二吡咯亚甲基)进行解络,以高产率提供双吡喃。这是通过在回流条件下在 CH3CN/CH3OH 中用不同的路易斯酸(例如 ZrCl4、TiCl4、AlCl3、Sc(OTf)3 或 SnCl4)处理 F-BODIPY 来实现的。这种合成策略对不同类型的 F-BODIPY 是有效的,例如中-芳基取代的 BODIPY、3-吡咯基 BODIPY、功能化的 3-吡咯基 BODIPY、π-扩展吡咯基 BODIPY、空间拥挤的 BODIPY 和 25-oxasmaragdy 的 BF2 复合物.
