|Abstract:||A simple 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 BODIPYs, 3-pyrrolyl BODIPYs, functionalized 3-pyrrolyl BODIPYs, -extended pyrrolyl BODIPYs, sterically crowded BODIPYs, and the BF2 complex of 25-oxasmaragdyrin.|
