Synthesis of 1-Butyl-2,3,4,5-tetraphenyl-2,4-cyclopentadiene and its Sodium, Thallium(I) and Iron(II) Complexes

1-Butyl-2,3,4,5-tetraphenyl-2,4-cyclopentadiene (3) is prepared starting from 2,3,4,5-tetraphenylcyclopentadien-1-one which forms 1-butyl-1-hydroxy-2,3,4,5-tetraphenylcyclopentadiene (1) by reaction with BuLi followed by acid hydrolysis. 1 and HBr give 1-bromo-1-butyl-2,3,4,5-tetraphenylcyclopentadiene (2), which in its turn reacts with BuLi and H2O/H+ to yield 3. Treatment of 3 with NaNH2, TlOEt or FeCl2 yields Na[C5Ph4Bu] (4), Tl[C5Ph4Bu] (5) and the corresponding ferrocene Fe[C5Ph4Bu]2 (6), respectively. The 1H and 13C NMR spectra of the new compounds are reported and discussed.
