在此,吡啶并四齿配体 3,6,9-三甲基-3,6,9,15-四氮杂双环[9.3.1]五十六-1(15),11,13-三烯,PyNMe3,用于分离和结构表征明确的有机金属 Ni(II) 和 Ni(III) 配合物,其带有 cycloneophyl 片段(烷基/芳基 C-供体配体)。此外,光谱和低温质谱研究表明瞬态 Ni(IV) 有机金属络合物的形成,并讨论了其与 C-C 和 C-O 键形成反应性研究的相关性。
Herein, the pyridinophanetetradentate ligand 3,6,9-trimethyl-3,6,9,15-tetraazabicyclo[9.3.1]pentadeca-1(15),11,13-triene, PyNMe3, is used to isolate and structurally characterize well-defined organometallic Ni(II) and Ni(III) complexes bearing the cycloneophyl fragment, an alkyl/aryl C-donor ligand. Furthermore, spectroscopic and cryo-mass spectrometry studies suggest the formation of a transient Ni(IV) organometallic complex, and its relevance to C–C and C–O bond formation reactivity studies is discussed.
