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.
期刊介绍:
Zeitschrift fuer Naturforschung B (ZNB) publishes novel research in all areas of inorganic chemistry, organic chemistry, and analytical chemistry. In particular, the journal focuses on solid state chemistry, coordination chemistry, main group element chemistry, synthetic organic chemistry, natural product chemistry and, to a lesser extent, on analytical chemistry. For more than 65 years Zeitschrift fuer Naturforschung B has been open to contributions from all fields of experimental and theoretical chemistry. Zeitschrift fuer Naturforschung B publishes 12 issues per volume/year. Sometimes double issues occur.
Topics
Solid state chemistry
Coordination chemistry
Main group element chemistry
