η5-Cyclopentadienylcobalt-η4-tetraphenylbutadienes RC5H4CoC4H2Ph4 (IIa-d: a R = H; b R = Et; c R = iPr; d R = PhCH2) have been prepared by simultaneous electrolysis of a respective substituted cyclopentadiene RC5H5 and diphenylacetylene in acetonitrile containing up to 0.5% water, using a cobalt anode. The action of iodine on IIa-d results in the elimination of the tetraphenylbutadiene ligand and the formation of diiodides (RC5H4CoI2)2 (IIIa-d). The reaction of IIa with iodine in the presence of electron donor ligands leads to the formation of complexes CpCoI2L, (L = Ph3P, Py, Me2S, dppe), [CpCoIL2]+I-3 (L2 = dipy, phen), (CpCoI2)2L (L = dppe).
