Abstract
With the new chiral phosphine ligand DBUP, obtained from DBU and Ph(2)PCl, a remarkable anion effect was observed on the diastereoselective formation of the bischelated complexes Ni(DBUP)(2)(n) (X = Cl, Br, n = 2; X = NiCl(4), n = 1), which are active ethylene oligomerization catalyst precursors.
摘要
使用从 DBU 和 Ph(2)PCl 得到的新的手性膦配体 DBUP，在二配位配合物 Ni(DBUP)(2)(n)（X = Cl、Br、n = 2；X = NiCl(4)、n = 1）的非对映选择性形成中观察到显著的阴离子效应，这些配合物是活性的乙烯齐聚催化剂前体。
