: The utilization of [Cp''2Zr(η1:1-E4)] (E = P (1a), As (1b), Cp'' = 1,3-di-tertbutyl-cyclopentadienyl) as phosphorus or arsenic source, respectively, gives access to novel stable polypnictogen transition metal complexes at ambient temperatures. The reaction of 1a/1b with [CpRNiBr]2 (CpR = CpBn (1,2,3,4,5-penta-benzyl-cyclopentadienyl), Cp''' (1,2,4-tri-tertbutyl-cyclopentadienyl)) was studied, to yield novel complexes depending on steric effects and stoichiometric ratios. Besides the transfer of the complete En unit, a degradation as well as aggregation can be observed. Read More
