Supersilyl as an effective monodentate ligand to stabilize four-coordinate manganese(ii) complexes†
Abstract
Supersilyl, –Si(SiMe3)3, serves as an effective ligand to afford a series of four-coordinate manganese(II) complexes. A dinuclear complex, [(THF)Mn{Si(SiMe3)3}(μ-Br)]2 (2), was readily synthesized by the reaction of MnBr2 with KSi(SiMe3)3. A subsequent ligand exchange of Br in 2 to –OtBu, methyl, or hydride afforded the corresponding manganese(II) complexes.
