Reaction Steps

1.36 g, 5.26 mmol of 1,2-bis(2-indenyl)ethane, prepared as described in the above reported Synthesis 1(a), were dissolved in 25 mL THF and cooled to −10° C. 5.5 ml of a 1.6 M solution of BuLi in hexane (8.8 mmoles) were added and the resulting orange/brown solution was stirred for 2 hours, at room temperature. To the obtained ;mixture was added, by means of a cannula, a solution of 1.1 ml of EtI (7.1 mmol) in 10 ml THF, at −10° C. After 2 hours, the THF was removed under vacuum, and Et2O was added. The thus obtained ether solution was washed 3 times with a saturated solution of NaHCO3 and 3 times with a saturated aqueous solution of NaCl. After drying over MgSO4, 1.46 g of 1,2-bis(1-ethyl-2-indenyl)ethane was isolated, in the form of a yellow oil. 1H NMR and GC showed that it consisted of the three possible double bond isomers.
