Ferrocenylaryl- or ferrocenylheteroarylphosphines [Fe1-PPh2(spacer)-2-NMe2CH2C5H3}(C5H5)] (spacer = 1,4-phenylene (rac-6), 1,3-phenylene (rac-7), 4,4'-biphenylene (rac-8), 2,5-thienylene (rac-9)) were prepared in a facile two-step sequence starting with Negishi cross-coupling between N,N-dimethylaminomethylferrocene and aryl halide phosphine oxides, Br-spacer-P(O)Ph-2, by reduction with trichlorosilane. All products were characterized spectroscopically (H-1, C-13, and P-31 NMR, MS, FTIR), and rac-6, the corresponding phosphine oxide rac-2, and rac-9 were also characterized by X-ray crystallography. Furthermore, the redox properties of rac-2-9 were studied by cyclic voltammetry.
