Synthesis and Reactivity of NiII(Phpy)2 (Phpy = 2-Phenylpyridine)
摘要:
This article describes the synthesis and reactivity of Ni-II(Phpy)(2) (Phpy = 2-phenylpyridine) with a variety of oxidants, including O-2, Br-2, PhICl2, N-fluoropyridinium salts, Cu-II salts, and N-halosuccinimides. High-oxidation-state Ni intermediates were not detected in any of these transformations. In all cases, the major organic product resulted from oxidatively induced C C bond formation to generate the Phpy Phpy dimer. Traces (2-16%) of organic products resulting from C-O, C-Br, C-Cl, and C-N bond-forming reductive elimination were also observed.
