R. Vollmerhaus et al., PREPARATION AND CHARACTERIZATION OF CATIONIC NICKEL INDENYL COMPLEXES[(1-METHYLINDENYL)NILL'](+), Organometallics, 16(22), 1997, pp. 4762-4764
The cationic complexes [(1-Me-Ind)Ni(PPh3)(L)](+) (1-Me-Ind = 1-methyl
indenyl; L = PPh3, PMe3, or MeCN) have been prepared and characterized
spectroscopically and by nt ans of single-crystal X-ray structural an
alysis in the case of [(1-Me-Ind)Ni(PPh3)(PMe3)]AlCl4. The in-situ-gen
erated cations dimerize ethylene.
