Reactions of [CpCo(PPh3)2](Cp=η5-cyclopentadienyl) with conjugated diacetylenes were investigated in terms of the synthesis of π-conjugated organometallic polymers. The reaction of an α,β-diyne, PhCCCCPh, gave three geometric isomers of dialkynylcobaltacyclopentadienes, 1a-c, and an insoluble polymeric product, 1d. A 2,4-dialkynyl complex, 2, and a 2,5-dialkynyl complex, 3, were obtained solely from Me3SiCCCCSiMe3 and MeCCCCMe, respectively. 1,1′-Bis(trimethylsilylethynyl)-4,4′-biphenyl afforded two isomers of 1,3-dialkynylcyclobutadiene complexes, 4a and 4b. The stability of the one-electron oxidized forms of the cobalacyclopentadiene and cyclobutadiene complexes was examined by cyclic voltammetry.
