Procedure

1,2,4,5-Tetraphenyl-3-p-vinylphenylcyclopenta-1,3-diene was prepared from 37.8 g (0.098 mol) of 2,3,4,5-tetraphenylcyclopent-2-enone and 0.5 mol of p-vinylphenyllithium (from 7 g (1 mol) of Li and 91.52 g (0.5 mol of bromostyrene) in 300 ml of ether and was purified analogously to 1,2,3,4-tetraphenyl-5-p-vinylphenylcyclopenta-1,3-diene. (Yield: 37 g (80%))
