  Versatile Coordination Modes and Transformations of the Cyclooctatriene Ligand in Ru(C₈H₁₀)L₃ (L = Tertiary Phosphine)

  摘要：

  Reaction of Ru(eta(4)-C8H12)(eta(6)-C8H10) (1) or Ru(eta(4)-C8H11)(2) (2) with tertiary phosphines gives Ru(eta(4)-C8H12)L-3 [L = PMe3 (4a), PMe2Ph (4b), PEt3 (4c), PEt2Ph (4d), P(n-Bu)(3) (4e)]. The cyclooctatriene moiety in 4a oxidatively adds to the ruthenium, giving RU(6-eta(1):1-3-eta(3)-C8H10)L-3 [L = PMe3 (3a), PMe2Ph (3b)]. Complexes 4c-e dissociate one phosphine ligand in solution, affording the (hydrido)ruthenium complexes RuH(eta(5)-C8H9)L-2 [L = PEt3 (5c), PEt2Ph (5d), P(n-Bu)(3) (5e)]. Whereas prolonged heating of 4c at 70 degrees C caused disproportionation of the eta(4)-C8H10 moiety giving a mixture of the cyclooctatetraene complex Ru(eta(4)-C8H8)(PEt3)(3) (6) and RuH(eta(5)-C8H11)(PEt3)(2) (7), heating of 1 with PEt3, 4c, or 4d in the presence of 1,5-C8H12 at 70 degrees C gave Ru(eta(4)-bicyclo[4.2.0]octst-2,4-diene)L-3 [L = PEt3 (8a), L = PEt2Ph (8b)]. The molecular structures of 3b, 4c, 6, and 8b have been established by X-ray structure analysis.

  (η4-Enone)ruthenium(0) complexes, Ru[η4-CH2CHC(R)O](PEt3)3 (R = H (3), Me (4)), are prepared by the reactions of Ru(η4-1,5-COD)(η6-1,3,5-COT) (1)/PEt3 and Ru(η4-1,3,5-COT)(PEt3)3 (2) with allylic alcohols such as allyl alcohol and 3-buten-2-ol, respectively. Hydrogen transfer from external allyl alcohol to the coordinated η4-3-buten-2-one ligand in 4 leads to the formation of 2-butanone and 3, suggesting

  Reactions of [Ru(1,5-COD)(1,3,5-COT)] (1) (COD = cyclooctadiene, COT = cyclooctatriene) with benzo[b]thiophene, thiophenes, benzo[b]furan, and furans in the presence of PEt3 result in the regioselective C-H bond cleavage of these heterocyclic compounds giving [Ru(1-5-eta(5)-C8H11)(R)(PEt3)(2)] [R = 2-benzo[b]thienyl (4a), 2-thienyl (4b), 5-(2-ethoxylcarbonyl)thienyl (4c), 5-(2-acetyl)thienyl (4d), 5-(3-acetyl)thienyl (4e), 2-benzo[b]furyl (5a), 2-furyl (5b), 5-(2-acetyl)furyl (5c)]. Similar treatments of I with indoline and pyrrole lead to cleavage of the N-H bond giving [Ru(1-5-eta(5)-C8H11)(R)(PEt3)(2)] [R = 1-indolyl (6a), 1-pyrrolyl (6b)]. The time-course study for the reaction of 1/PEt3 with benzo[b]thiophene monitored by use of NMR suggests prior formation of a zero-valent complex [Ru(1-4-eta(4)-1 3,5-COT)(PEt3)(3)] (2a) followed by production of 4a. Kinetic study reveals that the rate of the reaction of 2a with benzo[b]thiophene is the first-order dependence on [2a], [benzo[b]thiophene], and [PEt3](-1), respectively. This fact suggests prerequisite dissociation of PEt3 from a coordinatively saturated complex 2a giving a vacant site for interaction of Ru center with benzo[b]thiophene. (C) 2003 Elsevier B.V.
