Abstract

We report eight new A₂B-type (Mⁿ⁺) corrolate compounds (two structural studies) that include the oxo[5,15- bis(pentafluorophenyl)-10-R-corrolatochromium(V)] [R = 2-/3-thienyl (1a/2a), 3-thianaphthyl (3a)] species. The first examples of meso-A₂ (thienyl)- and Cr-A₂B-corrole types are represented herein. Characterization includes cyclic voltammetry, electron paramagnetic resonance, 2D (¹H and ¹³C) NMR, and UV-vis spectroscopy, mass spectrometry, and elemental analysis. Compounds 1a-3a have enabled analyte binding capacity studies. [Cu²⁺⋯O=Cr(cor)] binding represents a new selective mode of corrole-based detection, whereas free-base A ₂B-corroles exhibited limited Mⁿ⁺ selectivity. The 10-position substitution affects optical profiles In analyte titrations. A limited amount of PPh₃ O-atom uptake from [O=Cr(cor)] was also demonstrated.
