Abstract

Abstract : A remarkable helical complex with a chelating Cp-NHC ligand has been synthesised via olefin metathesis in the Ni(ii ) coordination sphere. Abstract : A remarkable nickelacycle has been synthesised via olefin metathesis of the α, ω-diene complex [Ni(η 5 -C5 H4 R)(Br)(NHC)] (R = C(CH3 )2 CH2 CHCH2, NHC = 1-(6-hexenyl)-3-(2, 4, 6-trimethylphenyl)-imidazol-2-ylidene). Single-crystal X-ray analysis reveals a helical shape of the molecule and stretching of some interatomic distances in the Ni(ii ) coordination sphere. The Cp-NHC tethered complex shows catalytic activity resembling that of the parent complexes.
