Abstract
(Cyclopentadiene pentayl)pentakis[(1,4-phenylene)alkanones] C5H(C6H4C(0)R-4)5 (R=CH3 (1a), C3H7 (1b), C5H7 (1c), C7H15 (1d)) react with N2H4(H2O)/KOH or Et3SiH/ CF3COOH to yield the oxygen free ligands C5H(C6H4CH2R-4)5 (2a, 2b, 2c and 2d), which after reaction with NaNH2 give the corresponding sodium salts Na[C5(C6H4CH2R-4)5] (3a, 3b, 3c and 3d). The sodium salts Na[C5(C6H4C(O)R-4)5] (R=CH3 (4a), C5H11 (4c) and 3a react with InCl to give In[C5(C6H4C(O)R-4)5] (5a, 5c) and In[C5(C6H4CH2R-4)5] (6a). 2a, 2b, 2c and 2d react with TlOC2H5 yielding Tl[C5(C6H4CH2R-4)5] (7a, 7b, 7c and 7d). The 1H and 13C NMR spectra of the new compounds are reported and discussed.Keywords
