Summary

The polymers 3 having pyridine moieties in the main chain were synthesized by the reaction of the organocobalt polymers 1 having cobaltacyclopentadiene moieties in the main chain with various nitriles 2. When brown colored 1 and excess 2 were heated in tetrahydrofuran at 80°C for 24 h and then at 150°C for 12 h in a sealed tube, the polymers 3 were obtained by the precipitation with methanol in good yields. From the spectroscopic measurements, the resulting polymers 3 were found to contain 35–90% of the pyridine moieties depending on the structures of 1.

  20. In the 13C-NMR spectra of 3Ab and 6, the peaks for the Cp were appeared at the same chemical shift (83 ppm).

  21. Concerning on the synthesis of the organocobalt polymers, the diynes bearing electrondonating substituents tends to increase the content of CpCbCo unit in the resulting polymers in comparison with those bearing electron-withdrawing substituents. Namely, the CpCbCo-content in the polymers bearing electron-donating substituents is higher than those bearing electron-withdrawing groups. See, ref (8b).
