Sn(IV)-corroles reversibly bind carboxylates in the axial position

Abstract

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.
