  Regioselective CH or NH bond cleavage reactions of heterocyclic compounds by [Ru(1,5-COD)(1,3,5-COT)]/monodentate phosphine

  摘要：

  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.
