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 mol) were slowly added. The resultant violet suspension was stirred for three hours at room temperature and then added dropwise to a mixture of 0.46 g of chromium(III) chloride 3THF (1.23 mmol) in 50 ml of THF. Once this addition was complete the mixture was stirred for a further 16 hours. The solvent was removed in vacuo and the resultant solid extracted several times with hot toluene on a G4 frit. Once the solvent had been distilled off from the combined extracts the product was obtained as a green powder. This was washed several times with hexane and dried under HV, giving 0.22 g of dichloro[1-(8-quinolyl)indenyl]chromium(III) (50%).
