We present the synthesis of Sn(IV)-corrole complexes that bind to carboxylate moieties reversibly, via axial ligation. The systems have been predominantly characterized using ¹H NMR spectroscopy, X-ray crystallography, and MALDI mass spectrometry. The dynamic nature of the Sn(IV)−O₂CR bond has been studied in solution using 2D-NMR spectroscopy.

Sn(IV)-咔咯在轴向位置可逆地结合羧酸盐

我们提出了 Sn(IV)-corrole 复合物的合成，该复合物通过轴向连接可逆地与羧酸酯部分结合。该系统主要使用¹ H NMR 光谱、X 射线晶体学和 MALDI 质谱进行表征。_{已使用 2D-NMR 光谱在溶液中研究了 Sn(IV)−O 2} CR 键的动态性质。
