(Bu2P)-Bu-t-P=P(Me)Bu-t(2) (1) forms with (Et3P)(2)NiCl2 (2) and Na(Nph) the [mu-(1,3: 2,3-eta-(Bu2P4Bu2)-Bu-t-Bu-t)Ni(PEt3)Cl}(2)] (3) as main product. Using Na/Hg instead as reducing agent the Ni-0 compounds [eta (2)-(Bu2P)-Bu-t-P}Ni(PEt3)(2)] (4), [eta (2)-(Bu2P)-Bu-t-P=P-(PBu2)-Bu-t}Ni(PEt3)(2)] (5) and [(Et3P)Ni(mu -(PBu2)-Bu-t)](2) (6) with four-membered Ni2P2 ring result. [eta (2)-C2H4}Ni(PEt3)(2)] yields with 1 also 4. The compounds were characterized by H-1 and P-31H-1} NMR investigations and 3 also by a single crystal X-ray analysis. It crystallizes triclinic in the space group P (1) over bar with a = 1129.4(2), b = 1256.8(3), c = 1569.5(3) pm, alpha = 72.44(3)degrees, beta = 70.52(3)degrees and gamma = 74.20(3)degrees.
(Bu2P)-Bu-t-P=P(Me)Bu-t(2) (1) 与 (Et3P)(2)NiCl2 (2) 和 Na(Nph) 反应,生成主产物 [μ-(1,3:2,3-η(Bu2P4Bu2)-Bu-t-Bu-t)Ni(PEt3)Cl}(2)] (3)。使用 Na/Hg 作为还原剂时,生成 Ni-0 化合物 [η(2)-(Bu2P)-Bu-t-P}Ni(PEt3)(2)] (4)、[η(2)-(Bu2P)-Bu-t-P=P-(PBu2)-Bu-t}Ni(PEt3)(2)] (5) 以及含有四元 Ni2P2 环的 [(Et3P)Ni(μ-(PBu2)-Bu-t)](2) (6)。[η(2)-
C2H4}Ni(PEt3)(2)] 与 1 反应生成 4。这些化合物通过 H-1 和 P-31H-1} NMR 实验表征,3 还通过单晶 X 射线分析表征。该化合物为三斜晶系,空间群为 P (1) over bar,晶格参数为 a = 1129.4(2) pm,b = 1256.8(3) pm,c = 1569.5(3) pm,α = 72.44(3)°,β = 70.52(3)°,γ = 74.20(3)°。
