AI Article Synopsis
- The study explores ligand-exchange reactions involving a manganese(II)cyclopentasilane complex, revealing two distinct reaction pathways based on the ligands used.
- In situations where aryl isocyanides are present, manganese(0) bis(η-disilene) complexes are formed, while ligands like CNBu or pyridine lead to stable manganese(II) complexes that maintain the cyclopentasilane structure.
- The thermolysis of the bis(η-disilene) complex, when mixed with mesityl isocyanide, results in a cyclotetrasilane through dimerization, and introduces a new manganese(II) complex featuring a unique tridentate ligand structure.
Article Abstract
Ligand-exchange reactions on a mangana(II)cyclopentasilane complex that contains two THF ligands with aryl isocyanides led to the formation of manganese(0) bis(η-disilene) complexes via a retrocyclization. In stark contrast, ligand-exchange reactions with CNBu, an N-heterocyclic carbene, or pyridine-based ligands furnished manganese(II) complexes wherein the manganacyclopentasilane framework remained intact. The thermolysis of the obtained bis(η-disilene) complex in the presence of mesityl isocyanide led to the formation of a cyclotetrasilane via the formal dimerization of the two η-disilene moieties. The insertion of a mesityl isocyanide into the Mn-Si bond results in the formation of a manganese(II) complex supported by a [SiCSi]-type tridentate ligand scaffold.
