  摘要：

  New and improved procedures are reported for the synthesis of [M(DBCOT)(mu-Cl)](2) (M = Rh, Ir; DBCOT = dibenzo[a,e]cyclooctatetraene) from MCl(3)(H(2)O)(x) or [M(COD)(mu-Cl)](2) and DBCOT. Treatment of [M(DBCOT)(mu-Cl)](2) with [(LAu)(3)(mu-O)]BF(4)(L = PPh(3), P(t)Bu(3)) yields the mixed-metal oxo complexes [M(DBCOT)(mu(4)-O)(AuL)(2)](2)(BF(4))(2). Dimeric [Rh( DBCOT)(mu-OH)](2) is obtained from the reaction of [M( DBCOT)(mu-Cl)](2) with KOH in EtOH/H(2)O. All complexes except [Rh(DBCOT)(mu-Cl)](2) have been structurally characterized by single crystal X-ray diffraction. (c) 2007 Elsevier B.V. All rights reserved.

  reversibly decomplexes in solution so that the two faces of the olefin are exchanged; for Rh(CH2CMe2CH2CH═CH2)(DBCOT) (2), the activation parameters for olefin decomplexation are ΔH‡ = 19 ± 1 kcal·mol–1 and ΔS‡ = 8 ± 4 cal·mol–1 K–1. Spin saturation transfer studies show that the decomplexation preserves the broken symmetry of the DBCOT ligand, which suggests that the olefin decomplexation in 2 most
