Syntheses and Characterization of 1,1'-Bis(3-Pyridylethynyl)Ferrocene and 1,1'-Bis(4-Pyridylethynyl)Ferrocene

Two novel disubstituted ferrocene, 1,1'-bis(3-pyridylethynyl)ferrocene 1 and 1,1'-bis(4-pyridylethynyl)ferrocene 2, were synthesized and fully characterized by elemental analysis, 1H NMR, 13C NMR, IR, and X-ray crystallography. Compound 1crystallizes in monoclinic, space group Cc, a=17.26Å, b=9.77Å, c=10.85Å, β=105.45; R1 =0.0399, wR2=0.1077, GooF=1.023. The two arms of the ferrocene are parallel, which will play an important role both in the coordination chemistry and electronic communication of the ferrocene.
