 Title    .4-Bis(4-acylphen-1 -yl)  
 Abstract    -1,3-cy clopentadiene und 1.2.3.4-Tetra(4-alkylphen-l-yI)-1,3-cyclopentadiene und deren Natrium-, Thallium(I)-und Eisen(II)-Komplexe 1.4-B is(4-acylphen-1 -y l)-1,3-cyclopentadienes and 1,2,3,4-Tetra(4-alkylphen-l-yl)-1,3-cyclopentadienes and their Sodium , T hallium (I) and Iron(II) C om plexes 1,4-D iphenyl-1,3-cyclopentadiene reacts with acyl chlorides RC(0)C1 (R = CH 3 (a), C5H m (c)) to form the corresponding l,4-bis(4-acylphen-l-yl)-l,3-cyclopentadienes C5H4(C6H4C (0)R)2 (la , lc), which upon treatment with NaNH2 or with T10C2H5 af­ ford the corresponding sodium complexes Na[C5H3(C6H4C (0)R)2] (2a, 2c) or thallium(I) derivatives T1[C5H3(C6H4C (0)R)7] (3a, 3c). The reaction of l,l',3,3'-tetraphenylferrocene with CH 3C (0)C1 results in the formation of Fe[C5H ,{ C (0)C H 3}{(C 6H4C (0)C H 3)2}]-[C5H 3{(C 6H4C (0)C H 3)2}] (5), whereas 2c and FeCl2 give Fe[C5H3(C6H4C(0)C5H M)2]2 (4c). The all-para-acylated tetraphenylcyclopentadienes C5H 2(C6H4C (0)R)4 (R = CH3 (a), C3H7 (b)) react with K[N2H4OH] to produce the ligands C5H2(C6H4CH 2R)4 (6 a, 6 b), which undergo reactions with NaNH2 and T10C2H3 to yield the sodium and thallium(I) salts, Na[C5H2(C6H4C H 2R)4] (7a, 7b) and T1[C5H2(C6H4CH2R)4] (8 a, 8 b), respectively. 7a and 7b react with FeCl2 to produce the corresponding ferrocenes Fe[C5H(C6H4CH2R)4]2 (9a, 9b). The 1H and l3C NMR spectra of the new compounds are reported and discussed.
