OP-III-40CYCLIC TRIMERIZATION AND LINEAR OLIGOMERIZATION OF ALKYNESBY (MONOCYCLOPENTADIENYL)NICKEL(I) COMPLEXESSaraev V.V., Kraikivskii P.B., Vilms A.I., Zelinskii S.N., Matveev D.A., Fedonina A.A.,Kuzakov A.S., Lammertsma K. 1Irkutsk State University, Irkutsk, Russia1 Vrije University, Amsterdam, the NetherlandsE-mail: saraev@chem.isu.ruNickelocene NiCp 2 in combination with organolithium compounds LiR is an effectivecatalyst for oligomerization and polymerization of alkynes [1]. The catalyst formationinvolves reduction of nickelocene giving the high reactive Ni(I) monocyclopentadienylcomplexes that in the absence of stabilizing ligands transform to bi-, tri-, tetra-, andpolynuclear clusters [2].This paper reports establishing the structures of the paramagnetic mononuclear complexes(η 5 -cyclopentadienyl)nickel(I) with triphenylphosphine, 2,2’-bipyridyl and 1,5-cyclooctadieneof composition CpNiL 2 (L = PPh 3 , bipy/2, COD/2), prepared through contradisproportionbetween NiCp 2 and corresponding NiL 4 complexes in toluene solutions, and their reactionswith phenylacetylene (PA) and diphenylacetylene (DPA).EPR spectroscopy showed that the CpNiL 2 complexes (L = PPh 3 , bipy/2) have the mainmolecular axis normal to the L-Ni-L plane, so these complexes should be regarded asderivatives of the D 3h symmetry trigonal structures disturbed by the Cp ligand. A magneticnonequivalence of the 31 P nuclei in the CpNi(PPh 3 ) 2 complex was revealed. It is bought aboutby the effect of electron - vibration interaction in a tricoordinate structure being in a pseudodegeneratedelectron state (Jahn-Teller pseudo-effect). In the complex CpNi(COD) the mainaxis goes through the center of the Cp ring and this complex should be regarded as aderivative of the C 5V symmetry pentagonal structure disturbed by the COD ligand.It was shown that phenylacetylene reacts with the CpNi(PPh 3 ) 2 complex (molar ratio PA/Ni =1-2) via the substitution of phosphine ligands by phenylacetylene to form the π-alkynecomplex CpNi( PhC ≡ CH ) 2 which in toluene solutions according to EPR data exists in theforms of two isomers different in the mutual orientation of the unsaturated hydrocarboncoordinated molecules. In time the Ni(I) π-alkyne complex turns to diamagnetic structures.When diphenylacetylene reacts with the CpNi(PPh 3 ) 2 complex in the same conditions the413
