Preparation and characterization of nickel complexes with η-indenyl ligands bearing a pendant aminoalkyl chain

The aminoindenyl complexes {Ind(CH2)3,4N(t-Bu)H}Ni(PPh3)Cl (7, 8) and {Ind(CH2)2,3NMe2}Ni(PPh3)Cl (9, 10) have been prepared and characterized by spectroscopy and, in the case of 7 and 9, by X-ray structural studies. Although there is no interaction between the Ni center and the amine moiety of these complexes in the solid state, solution spectra point to a temperature-dependent, intramolecular N→Ni coordination in complex 9 and a more facile, intermolecular interaction in 10. Abstraction of Cl- from these complexes led to the formation of the cations [{η3:η0-Ind(CH2)3,4N(t-Bu)H}Ni (PPh3)2]+ and [{η3:η1-Ind(CH2) 2,3NMe2}Ni(PPh3)]+ (11, 12). The origin of the observed differences in the reactivities of these complexes is discussed in terms of the lengths of the tether and the nature of the N-substituents.
