The reactions of σ,η<sup>3</sup>-butadienylruthenium complexes with donor ligands and protons: structures of [RuC(Ph)C(Ph)-η<sup>2</sup>-{(Z)-C(Ph)CH(Ph)}{P(OMe)<sub>3</sub>}(η-C<sub>5</sub>H<sub>5</sub>)] and [RuC(O)C(Ph)C(Ph)-η<sup>2</sup>-{(Z)-C(Ph)CH(Ph)}{P(OMe)<sub>3</sub>}(η-C<sub>5</sub>H<sub>5</sub>)]

σ,η3(5e)-Butadienylruthenium complexes behave as masked σ,η2(3e)-butadienyl complexes in their reactions with P(OMe)3 and PhC2Ph, whereas, protons react on the ‘inside’ of the σ,η3-butadienyl chain at the α-carbenoid carbon; attempts to expel P(OMe)3 thermally from the resulting σ,η2(3e)-butadienyl complexes results instead in a zeta-H abstraction reaction.
σ,η 3(图5E)-Butadienylruthenium络合物表现为掩蔽σ,η 2在他们的反应(3E)-butadienyl配合物P(OME)3和光子晶体2的pH值,而质子上的σ的'内部'反应, η 3在α碳类卡宾链-butadienyl; 尝试驱逐P(OME)3从所得热σ,η 2(3E)-butadienyl络合物结果,而不是在的ζ-H抽提反应。
