    铑硫代磷酰基钳络合物中CO诱导的甲基迁移及其与基于膦的络合物的比较:S和P供体配体的发散作用
    摘要:
    阳离子铑(III)芳基 - 甲基络合物,带有基于硫代磷-SCS型钳配体,经受在加入CO的简易洄游插入,从而得到负载Rh(III)的芳基乙酰基配合物。这种反应性不同于膦基PCP和PCN型钳形配体的结构类似的Rh(III)芳基-甲基配合物,先前已证明添加CO会进行C–C还原消除,从而得到C– C混浊的Rh(I)配合物。DSC对SCS和PCP配合物中CO迁移插入的比较DFT研究表明,反应性差异源自SCS配体的硫原子相对于PCP配体的磷原子具有更高的亲电性。这导致SCS系统中Rh→COπ的反向捐赠减少,导致一氧化碳通透化,并促进了金属向一氧化碳的甲基迁移。在PCP系统中,它会增强Rh-CO键,从而增强OC→Rh→芳烃的σ贡献,从而削弱Rh–C本位键和促进金属对-C本位甲基迁移。

  • Exclusive C–C Oxidative Addition in a Rhodium Thiophosphoryl Pincer Complex and Computational Evidence for an η<sup>3</sup>-C–C–H Agostic Intermediate

    The room-temperature reaction between the Rh(I) precursor [Rh(COE)(2)(acetone)(2)]BF4 (COE = cyclooctene) and a new thiophosphoryl-based SCS pincer ligand leads to oxidative addition of an sp(2)-sp(3) C-C bond as the only observed outcome, despite the presence of accessible sp(3) C-H bonds. A DFT study reveals that the chemistry of the SCS system is controlled by pi repulsion between occupied rhodium d orbitals and the lone-pair electrons on the two sulfur atoms. This repulsion gives rise to the thermodynamic selectivity for C-C over C-H cleavage, as it is attributed to the higher electronegativity of a methyl versus hydride ligand, thereby allowing more effective release of excessive pi electron density. It is also demonstrated that the observed C-C and unobserved C-H cleavage pathways originate from a common intermediate that features a novel eta(3)-C-C-H agostic interaction. The COE ligand is shown to play an important role by greatly stabilizing this intermediate, making it the only available entry point to both reaction pathways.
