Abstract ESR study of the interaction between the components of the catalytic system Co(acac)2- PBu3-LiBu in the presence of butadiene revealed the formation of stable paramagnetic cobalt complexes containing a PBu3 ligand and butadiene molecules. Complexes (η3-R)2CoPBu3 (where R is allyl, crotyl, benzyl) have been synthesized by ordinary methodsin situ, in order to identify the structures of the complexes. ESR parameters and geometry of the central core have been determined. The influence of the nature of phosphine ligands on the parameters of the ESR spectra has been studied. The general regularities in the ESR spectra of (η3-R)2CoPBu3 and the complexes formed in the catalytic system have been revealed.
