A high-valent non heme μ-oxo MnIV dimer generated from a thiolate-bound MnII complex and O2
Abstract
This study deals with the unprecedented reactivity of<br/>dinuclear non heme Mn<sup>II</sup>–thiolate complexes with O<sub>2</sub>, which<br/>dependent on the protonation state of the initial Mn<sup>II</sup> dimer<br/>selectively generates either a di-μ-oxo or μ-oxo-μ-hydroxo Mn<sup>IV</sup><br/>complex. Both dimers have been characterized by different<br/>techniques including single-crystal X-ray diffraction and mass<br/>spectrometry. Oxygenation reactions carried out with labeled <sup>18</sup>O<sub>2</sub><br/>unambiguously shows that the oxygen atoms present in the Mn<sup>IV</sup><br/>dimers originate from O<sub>2</sub>. Based on experimental observations and<br/>DFT calculations, evidence is provided that these Mn<sup>IV</sup> species<br/>comproportionate with a Mn<sup>II</sup> precursor to yield μ-oxo and/or μ-<br/>hydroxo Mn<sup>III</sup> dimers. Our work highlights the delicate balance of<br/>reaction conditions to control the synthesis of non heme high-valent<br/>μ-oxo and μ-hydroxo Mn species from Mn<sup>II</sup> precursors and O<sub>2</sub>.
