Participants

Reaction Steps

6.85 g (181 mmol) of sodium borohydride and 40 ml of THF were added to a solution of 48.9 g (489 mmol) of ethylcyclopentadienyl lithium prepared from ethylcyclopentadiene and butyl lithium in THF (200 ml), followed by ice-cooling. 24.9 g (69 mmol) of tantalum pentachloride was added to the mixture, followed by refluxing for 4 hours. The solvent was distilled away in vacuo, and the residue was sublimated at 2.5 Pa/100° C. to obtain 8.80 g (yield: 34.2%) of a white solid.
