| Objective To investigate the activation of the C-H bond of N-naphthyl ferrocenylideneamine with CoMeL4(L=PMe3).Methods and Results Reaction of N-naphthyl ferrocenylideneamine with CoMeL4(L=PMe3) affords a new compounds, η2[N, C]-(1-N-naphthylferrocenylideneamine) tris(trimethylphosphine) cobalt(Ⅰ), which has been characterized by IR, 1H NMR spectra, and the crystal structure has been determined by means of X-ray diffraction, as far as our knowledge it is the first example of C-H activation in ferrocenylideneamine by electron-rich cobalt complexes.The crystal structure crystallized in monoclinic with the space group P21/n, a=10.692(2)Å, b=14.273(3)Å, c=19.719(4)Å, β=99.58(3)°.The cobalt atom is penta-coordinate in a trigonal bipyramidal geometry, with two phosphrous atoms and the imino group occupying the equatorial positions, and another phosphrous atom and the carbon atom of the naphthyl group taking the axial position.Conclusion A new Fe-Co binuclear complex was synthesized by C-H activation. |
