Abstract

5-Bromo-1,2,3,4-tetraphenyl-5-p-tolyl-1,3-cyclopentadiene (la), 5-Bromo-1,4-di-phenyl-2,3,5-tri-p-tolyl-1,3-cyclopentadiene (1b), 5-Bromo-1,2,3,4,5-penta-p-tolyl-1,3-cyclopentadiene (1c), 5-Bromo-1,2,3,4-tetraphenyl-5-p-bromophenyl-1,3-cyclopentadiene (1d), and 5-Bromo- 1,2,3,4-tetraphenyl-5-p-anisyl-l,3-cyclopentadiene (1e) react with ironpentacarbonyl in m-xylene to yield the corresponding ferrocenes 2a-2e. In the course of the purification procedure, reactions with HCl and the solvent m-xylene are observed which yield the mixed ionic sandwich complexes [(C 5 Ph 4 C 6 H 4 Me)Fe(C 6 H 4 Me 2 )] + Cl - (3a), [(C 5 Ph 2 (C 6 H 4 Me) 3 )Fe(C 6 H 4 Me 2 )] + Cl - (3b), [(C 5 (C 6 H 4 Me) 5 )Fe(C 6 H 4 Me 2 )] + Cl - (3c), [(C 5 Ph 4 C 6 H 4 Br)Fe(C 6 H 4 Me 2 )] + Cl - (3d), and [(C 5 Ph 4 C 6 H 4 OMe)Fe(C 6 H 4 Me 2 )] + Cl - (3e), respectively, along with the corresponding cyclopentadienes 1,2,3,4-tetraphenyl-5-p-tolyl-1,3-cyclopentadiene (4a), 1,4-diphenyl-2,3,5-tri-p-tolyl-1,3-cyclopentadiene (4b), l,2,3,4,5-penta-p-tolyl-1,3-cyclopentadiene (4c), 1,2,3,4-tetraphenyl-5-p-bromphenyl-l,3-cyclopentadiene (4d), and 1,2,3,4-tetraphenyl-5-p-anisyl-1,3-cyclopentadiene (4e). The compounds have been characterized by elemental analysis, IR, NMR, and mass spectra, and, in the case of 2c, by 1 3 C-CPMAS spectroscopy and X-ray powder diffractometry.
