  名称：

  Chiral annulated cyclopentadienyl ligands: Synthesis and crystal structure of both exo and endo Rh{η5-Cp′}(cod)} [Cp′=(4S,7R)-1,2,3-triphenyl-4,8,8-trimethyl-1H,4,5,6,7-tetrahydro-4,7-methanoindenyl]

  摘要：

  The title homochiral cyclopentadiene ligand C31H30 (i.e., Cp'H, 5) has been synthesised from camphor in four steps. The lithium salt of this ligand reacted with [Rh(cod)Cl](2) to give predominantly racemic (eta(4)-cycloocta-1,5-diene)[eta(5)-1,2,3-triphenyl-4-methyl-7-isopropyl- 1H-indenyl]rhodium although the desired RhCp'(cod) complex was formed in 20% yield as an equal mixture of endo 7a and exo 7b isomers. The X-ray structures of 7a and 7b have been determined at room temperature with use of Mo-K-alpha radiation (lambda = 0.71069 Angstrom). Both compounds crystallise in the orthorhombic space group P2(1)2(1)2(1) (D-2(4), No. 19); for compound 7a, a = 13.549(23) Angstrom, b = 14.490(25) Angstrom, c = 15.909(14) Angstrom, V = 3123(8) Angstrom(3), Z = 4 and D-c = 1.303 g cm(-3) and the structure was refined to R = 0.0488 on the basis of 2545 independent reflections. For the exo isomer 7b, a = 13.301(18) Angstrom, b = 15.599(32) Angstrom, c = 14.436(19) Angstrom, V = 2995(10) Angstrom(3), Z = 4 and D-c = 1.359 g cm(-3); the structure was refined to R = 0.0362 on the basis of 4620 independent reflections. Bromine reacts with the compounds 7a and 7b to give the corresponding [{Rh(Cp')}(2)(mu-Br-3)]Br-3. (C) 1998 Elsevier Science S.A.
