Reaction mixture composition studies, kinetic studies as well as theoretical calculations, indicate that the softer the carbonyl compound is, the faster it reacts with the softer phosphorus nucleophile and the slower it reacts with the harder amine nucleophile.

  • Lanthanide anilido complexes: synthesis, characterization, and use as highly efficient catalysts for hydrophosphonylation of aldehydes and unactivated ketones
    作者:Chengwei Liu、Qinqin Qian、Kun Nie、Yaorong Wang、Qi Shen、Dan Yuan、Yingming Yao
    DOI:10.1039/c4dt00522h
    日期:——
    Lanthanide anilido complexes stabilized by the 2,6-diisopropylanilido ligand have been synthesized and characterized, and their catalytic activity for hydrophosphonylation reaction was explored. A reaction of anhydrous LnCl3 with 5 equivalents of LiNHPh-iPr2-2,6 in THF generated the heterobimetallic lanthanide–lithium anilido complexes (2,6-iPr2PhNH)5LnLi2(THF)2 [Ln = Sm(1), Nd(2), Y(3)] in good isolated yields. These complexes are well characterized by elemental analysis, IR, NMR (for complex 3) and single-crystal structure determination. Complexes 1–3 are isostructural. In these complexes, the lanthanide metal ion is five-coordinated by five nitrogen atoms from five 2,6-diisopropylanilido ligands to form a distorted trigonal bipyramidal geometry. The lithium ion is coordinated by two nitrogen atoms from two 2,6-diisopropylanilido ligands, and one oxygen atom from a THF molecule. It was found that these simple lanthanide anilido complexes are highly efficient for catalyzing hydrophosphonylation reactions of various aldehydes and unactivated ketones to generate α-hydroxyphosphonates in good to excellent yields (up to 99%) within a short time (5 min for aldehydes, 20 min for ketones). Furthermore, the mechanism of hydrophosphonylation reactions has also been elucidated via1H NMR monitoring of reaction.
    稳定的2,6-二异丙基苯胺配体的镧系金属苯胺复合物已被合成和表征,并探讨了其在磷化氢化反应中的催化活性。无水LnCl3与5个等摩尔的LiNHPh-iPr2-2,6在THF中的反应生成了异质双金属镧系-锂苯胺复合物(2,6-iPr2PhNH)5LnLi2(THF)2 [Ln = Sm(1), Nd(2), Y(3)],收率良好。这些复合物通过元素分析、红外光谱、核磁共振(对于复合物3)和单晶结构测定进行了良好的表征。复合物1-3是同构的。在这些复合物中,镧系金属离子由来自五个2,6-二异丙基苯胺配体的五个氮原子协调,形成四面体畸变的三角双锥几何结构。锂离子则由两个2,6-二异丙基苯胺配体中的两个氮原子和一个THF分子中的氧原子协调。研究发现,这些简单的镧系苯胺复合物在催化各种醛和未活化酮的磷化氢化反应中具有高效率,能够在短时间内(醛为5分钟,酮为20分钟)生成α-羟基磷酸酯,收率良好至优异(高达99%)。此外,磷化氢化反应的机制也通过氢核磁共振监测反应得到了阐明。
