0.05 g of potassium hydride (1.23 mmol) were suspended in 20 ml of THF, and 0.3 g of 1-(8-quinolyl)indene (1.23 mmol) were added slowly. After stirring for three hours at room temperature, the obtained violet suspension was added dropwise to a mixture of 0.46 g of chromium(III) chloride×3THF (1.23 mmol) in 50 ml of THF, and subsequently the mixture was stirred for a further 16 hours. The solvent was removed in a vacuum and the solid thus obtained was extracted using hot toluene. After the solvent had been distilled off from the combined extracts, the product was in the form of a green powder, which was washed several times with hexane and dried in a high vacuum. 0.22 g of dichloro-[1-(8-quinolyl)indenyl]chromium(III) (50%) was obtained.
