| Abstract: | New biferrocenylpropane derivatives FcC(CH3)2Fc′-C≡C–R Fc?=?C5H5FeC5H4; Fc′?=?C5H5FeC5H3, R?=?C6H5 (L 1 ), Fc (L 2 )] and their complexes FcC(CH3)2Fc′-C≡C–R]Co2(CO)6] R?=?C6H5 (1); R?=?Fc (2)] have been synthesized by the Castro-Stephens coupling reaction and the reactions of ligands L 1 , L 2 with Co2(CO)8. Compounds L 1 , L 2 , 1 and 2 were characterized by elemental analysis, IR, 1H (13C) NMR and MS, and the molecular structures of ligands L 1 , L 2 were determined by X-ray single crystal analysis. The electrochemical properties of L 1 , L 2 , 1 and 2 demonstrate two or three resolved one-electron redox processes. |
