Rhenium-Sulfido and -Dithiolato Corroles: Reflections on Chalcophilicity.

ABSTRACT: The high-temperature (∼180 °C) reaction between free-base meso-triarylcorroles and Re₂(CO)₁₀, followed by exposure to PCl₃ and thiols (or elemental sulfur), affords rhenium-sulfido (ReS) corroles in 67-76% yields. The use of shorter reaction times, lower temperatures (∼130 °C), and a dithiol (e.g., ethane-1,2-dithiol) also allows the isolation of rhenium-dithiolato corroles, presumptive intermediates on the path to ReS corroles. The ReS corroles exhibit high thermal stability and two reversible oxidations and reductions in their cyclic voltammograms, with redox potentials nearly identical to those observed for analogous ReO corroles. The electrochemical HOMO-LUMO gaps of the complexes, at 2.2 eV, are consistent with ligand-centered oxidation and redu
