E₄ Transfer (E=P, As) to Ni Complexes.

ABSTRACT: The use of [Cp''₂ Zr(η^1:1 -E₄ )] (E=P (1 a), As (1 b), Cp''=1,3-di-tert-butyl-cyclopentadienyl) as phosphorus or arsenic source, respectively, gives access to novel stable polypnictogen transition metal complexes at ambient temperatures. The reaction of 1 a/1 b with [Cp^R NiBr]₂ (Cp^R =Cp^Bn (1,2,3,4,5-pentabenzyl-cyclopentadienyl), Cp''' (1,2,4-tri-tert-butyl-cyclopentadienyl)) was studied, to yield novel complexes depending on steric effects and stoichiometric ratios. Besides the transfer of the complete E_n unit, a degradation as well as aggregation can be observed. Thus, the prismane derivatives [(Cp'''Ni)₂ (μ,η^3:3 -E₄ )] (2 a (E=P); 2 b (E=As)) or the arsenic containing
