Enlarging the family of ferrocenylphosphine dinuclear rhodium complexes: synthesis and X-ray structure of a novel “A-frame”-type trimetallic Rh/Fe/Rh…
2004
Abstract The symmetrically substituted ligand 1,1 ′ -bis[di(5-methyl-2-furyl)phosphino]ferrocene ( 1 ) has been obtained from the bromophosphine BrP(Fu Me ) 2 and the dilithioferrocene/TMEDA adduct. The quantitative addition of this ferrocene derivative to the tetracarbonyl dimer [(CO) 4 Rh 2 {μ-(S t Bu) 2 }] leads, through decarbonylation, to the dinuclear rhodium complex [(CO) 2 Rh 2 {μ-(S t Bu) 2 }{μ- P , P -Fc[P(Fu Me ) 2 ] 2 }] ( 2 ) in high yield. A X-ray structure [ orthorhombic , space group P 2 1 2 1 2 1 ; a =11.2982(2) A, b =13.3165(3) A, c =27.2687(7) A] and the solution multinuclear NMR characterization are reported, which show that the rare “quasi-closed bridging” A-frame struc…
Aminomethyl-Substituted Ferrocenes and Derivatives: Straightforward Synthetic Routes, Structural Characterization, and Electrochemical Analysis
2013
A variety of aminomethyl-substituted ferrocenes and the parent compounds (iminomethyl)ferrocenes, azaferrocenophanes, and diferrocenylamines can be selectively synthesized from reductive amination of 1,1′-diformylferrocene or formylferrocene. The optimized one- or two-step reactions have delivered 13 new compounds, isolated in 65–97% yields, which include tertiary (ferrocenylmethyl)amines and azaferrocenophanes by using NaBH(OAc)3 as a mild reducing agent and (iminomethyl)ferrocenes and secondary (ferrocenylmethyl)amines by using LiAlH4. X-ray structures of representative members of these ferrocene derivative families have evidenced the preferred conformation adopted by ferrocene backbones,…
