本文提出了利用两步法合成烃基体积较大的对称和不对称1,2-二(二叔丁基膦)乙烷[d(t-Bu)pe]和1,2-二(苯基叔丁基膦)乙烷[Pb(t-Bu)pe]以及利用α,ω-双格氏试剂与PCl_3反应直接合成较大螯合环的1,4-二(磷杂环戊基)丁烷(dPCypb)和正丁基磷杂环戊烷[(n-Bu)(PCyp)]膦配体的新方法。并用通常的合成方法得到了这些配体的Pt,Ni金属有机配合物,其中[d(t-Bu)pe]PtCl_2,(dPCypb)PtCl_2,和[(n-Bu)(PCypP]PtCl_2,配合物进行了晶体和分子结构测定。讨论了配体的空间因素对配合物结构的影响。 In this paper, the synthesis of symmetric and asymmetric 1,2-di (tert-butylphosphino) ethane [d (t-Bu) pe] and 1,2-bis Butylphosphine) ethane [Pb (t-Bu) pe] and the direct synthesis of 1,4-bis (phospholane) butane with larger chelating ring by the reaction of α, (dPCypb) and n-butylphospholane [(n-Bu) (PCyp)] phosphine ligands. The Pt, Ni metal-organic complexes of these ligands were obtained by the usual synthetic methods, among which [d (t-Bu) pe] PtCl_2, (dPCypb) PtCl_2 and [(n-Bu) Crystal and molecular structure measurements were carried out, and the influence of the spatial factors on the structure of the complex was discussed.
