  Synthesis, crystal structures and use in ethylene oligomerization catalysis of novel mono- and dinuclear nickel complexes supported by (E)-N′-(1-(thiophen-2-yl)ethylidene)benzohydrazide ligand

  摘要：

  The coordination chemistry of Ni-II supported by (E)-N'-(1-(thiophen-2-yl)ethylidene)benzohydrazide ligand (HL) is reported and discussed. The crystal structure of ligand HL has been determined as well as those of three new Ni-II complexes (Ni(HL)(2)Br-2, NiL2 and mu-aquo-Ni2L4). The pseudo-octahedral bis(chelate) Ni(II) complex 2 (NiL2), in which unexpected and singular Ni center dot center dot center dot S interaction is observed, was evaluated as catalyst for the oligomerization of ethylene and found to provide ethylene dimers and trimers as primary products with a turnover frequency (TOF) of 31200 mol of C2H4 per mol. of Ni and per hour.
