Reaction Steps

1.1 g (37 mmoles) of potassium(2-tert-butyl-4,5-di(1,1-dimethylpropyl)imidazolate) dissolved in 25 ml of THF were added to 1 g (0.0037 moles) of ruthenium (pentamethylcyclopentadienide) chloride dissolved in 75 ml of dry THF and the resulting mixture stirred overnight at room temperature. The solvent was then removed by vacuum, 100 ml of dry hexane then added and the resulting mixture thoroughly stirred then filtered. The hexane was then removed by vacuum to yield 1.13 g of crude ruthenium (2-tert-butyl-di(1,1-dimethylpropyl)imidazolate). (pentamethylcyclopentadienide). Structure confirmed by GCMS, parent ion detected at 499 mu. The structure was also confirmed by X-ray structural analysis of a sample of crude material which was sublimed then recrystallized from hexane. This shows the imidazolate and cyclopentadienide anions to both be coordinated eta-5 to ruthenium, see FIG. 21.
