Silicon(II) Coordination Chemistry: N-Heterocyclic Carbene Complexes of Si2+ and SiI
Ligand swap: The exchange of N‐heterocyclic carbene (NHC) ligands at SiII centers is shown to provide access to a dicationic NHC complex of silicon(II), and an NHC adduct of the iodosilyliumylidene cation SiI+, [SiI(IiPr2Me2)(IDipp)]+ (see picture). Characterization studies led to the discovery of a...

Zusammenfassung: | Ligand swap: The exchange of N‐heterocyclic carbene (NHC) ligands at SiII centers is shown to provide access to a dicationic NHC complex of silicon(II), and an NHC adduct of the iodosilyliumylidene cation SiI+, [SiI(IiPr2Me2)(IDipp)]+ (see picture). Characterization studies led to the discovery of an unprecedented CH⋅⋅⋅Si anagostic interaction for [SiI(IiPr2Me2)(IDipp)]+. |
