Abstract

The ethylene molecule in the binuclear complex [bis(2-4η-phosphorinyl)nickel](η2 -ethylene)-P,P′-nickel (1) is displaced by 1-alkenes in an equilibration reaction to give the corresponding (η2 -1-alkene)nickel complexes 2-5. The NMR spectra of the octene complex 3 and the propene complex 6 are temperature dependent because of valence isomerization in the phosphorinyl group and rotation of the olefin. The binuclear structure is not maintained upon displacement of the ethylene by butadiene or isoprene. One nickel atom is displaced as the dodecatrienediylnickel complex 9 and the remaining bis(phosphorinyl)nickel fragment B reacts with insertion of the diene into one allyl-Ni bond to give 7 resp. 8. The molecular structure of 7 was determined by X-ray crystallography.
