| Аннотация |
The reactivity of unsymmetrical pyrazole-based PCN pincer Ni(II) halides has been tested in the presence of copper(II) halides as an oxidizing agent as well as with NaBH4 and LiAlH4 as a hydride source. While the reaction with CuX2 resulted into the generation of metastable PCN pincer Ni(III) species, the treatment of (tBuPCN)NiCl with NaBH4 led to the preparation and isolation of the borohydride complex (tBuPCN)Ni(BH4). Attempts to isolate nickel-hydride species upon treatment of (tBuPCN)NiCl with either NaBH4 or LiAlH4 invariably led to the formation of free PCN(H) ligand and metallic Ni(0) nanoparticles after an in situ reductive elimination from the (metastable) hydride derivative (tBuPCN)NiH. Finally, the halide complexes (pre-activated by MMAO) have been tested as homogeneous catalysts in ethylene oligomerization showing moderate activity (~ 14 103 molC2H4,molNi 1,h1) with the formation of evennumbered olefins (mainly C4eC10 fractions) as products. |
