A series of aluminium iminophosphoranylenamide complexes, [Me(2)Al{N(Ar)C(Ph)=CHP(Ph(2))=N-Ar(1)}] (Ar = Ph, Ar(1) = p-MeC(6)H(4) (9); Ar = Ph, Ar(1) = o-ClC(6)H(4) (10); Ar = Ph, Ar(1) = o-FC(6)H(4) (11); Ar = p-MeC(6)H(4), Ar(1) = o-FC(6)H(4) (12)), were synthesised by the reactions of ArN=C(Ph)CH(2)P(Ph(2))=NAr(1) (5-8) with AlMe(3) in toluene. Similar reactions between o-{ArN=P(Ph(2))}C(6)H(4)NHC(Ph)=CHP(Ph(2))=NAr (Ar = p-MeC(6)H(4), 13), and AlMe(3) in toluene generates aluminium iminophosphoranylanilide, 14. All new compounds were characterised by NMR spectroscopy and elemental analysis. The molecular structures of complexes 9 and 14 were further characterised by single-crystal X-ray structure determination. In the presence of benzyl alcohol (BnOH) each of the complexes is catalytically active for the ring-opening polymerisation (ROP) of ε-caprolactone (ε-CL), and complex 14 has the highest activity among them.
一系列的铝亚氨基磷酰胺配合物，[Me(2)Al{N(Ar)C(Ph)=CHP(Ph(2))=N-Ar(1)}]（Ar = Ph，Ar(1) = p-MeC(6)H(4)（9）；Ar = Ph，Ar(1) = o-ClC(6)H(4)（10）；Ar = Ph，Ar(1) = o-FC(6)H(4)（11）；Ar = p-MeC(6)H(4)，Ar(1) = o-FC(6)H(4)（12）），是通过 ArN=C(Ph)CH(2)P(Ph(2))=NAr(1)（5-8）与 AlMe(3)在甲苯中的反应合成的。在甲苯中，o-{ArN=P(Ph(2))}C(6)H(4)NHC(Ph)=CHP(Ph(2))=NAr（Ar = p-MeC(6)H(4)，13）和 AlMe(3)之间的类似反应也会生成铝亚氨基磷酰胺，14。所有新的化合物都通过 NMR 光谱和元素分析进行了表征。配合物 9 和 14 的分子结构通过单晶 X 射线结构测定进一步得到了表征。在苄醇（BnOH）的存在下，每种配合物对ε-己内酯（ε-CL）的开环聚合（ROP）都具有催化活性，其中 14 的活性最高。
