Synthesis and Characterization of Manganese(II) Complexes Supported by Cyclopentadienyl-Phosphine Ligand

Abstract

A series of manganese(II) complexes supported by cyclopentadiene-phosphine ligands have been synthesized and characterized. Reaction of potassium salts of cyclopentadiene-phosphine ligand (LK) with MnX2 provided dimeric complexes [LMn(μ-X)]2 (X = Cl, 1a; X = Br, 1b) in high yields. The monomeric complex [K(18-crown-6)][LMnCl2] (2) was obtained with the addition of 18-crown-6. [LMn(μ-Cl)]2 (1a) served as a precursor to dimeric amido and methyl manganese(II) complexes including [LMn(μ-NH2)]2 (3) and [LMn(μ-Me)]2 (4). Treatment of [LMn(μ-Cl)]2 (1a) with EtMgCl, PhMgBr or other reductants resulted in the formation of sandwich manganese(II) complex L2Mn (5). Complexes 1a,b, 2-5 were characterized by single-crystal X-ray structural analysis.
