with either bromine (dbchpH = 3,5-dibromo-6-chloro-2-pyridone) or trimethylsilyl (TMS) groups (dsichpH = 6-chloro-3,5-bis(trimethylsilyl)-2-pyridone) allows for the preparation of the Ru2(II,II) paddlewheel complexes Ru2(dbchp)4 (3) and Ru2(dsichp)4 (6), respectively, neither of which shows evidence of dimerization. Though the utilization of 3 is limited due to insolubility, complex 6 is soluble even
桨叶复合物Ru 2(chp)4 Cl(1-Cl,chp = 6-氯-2-氧吡啶鎓),经锌还原后,先前已显示为二聚为[Ru 2(chp)4 ] 2(2) ,进一步阻止了Ru 2(II,II)轴向位点的化学反应[ Inorg。化学 2015年,54,8571-8589]。chp配体在3和5位上被溴(dbchpH = 3,5-dibromo-6-chloro-2-pyridone)或三甲基甲硅烷基(TMS)基团(dsichpH = 6-chloro-3,5-bis(三甲基甲硅烷基)-2-吡啶酮)可用于制备Ru 2(II,II)桨轮配合物Ru 2(dbchp)4(3)和Ru 2(dsichp)4(6)均未显示二聚化的迹象。虽然的利用率3由于限于不溶性,复杂6是即使在通常的非配位溶剂中可溶的,形成κ稳定1个在CH -axial加合物2氯2(6-CH 2氯2的轴向)和表示证据与正癸烷的相互作用。轴向自
