一般描述

硝酸镧六水合物是过渡金属催化剂，广泛用于许多有机转化反应，例如丙酮化合物的化学选择性脱保护，醇、酚和胺与乙酸酐的酰化，α-氨基腈类化合物的合成反应。也可作为前体制备镧基纳米粒子。

应用

硝酸镧六水合物可用作下列反应的催化剂：
  • α羰基化合物、胺类和TMSCN通过一锅三组分偶联作用合成α-氨基腈。
  • 醛合成缩醛和偕二乙酸酯（乙酰缩醛）。
  • 无溶剂条件合成双吲哚基甲烷。
也可用作起始原料，用于电化学合成LaMnO3薄膜和溶剂热法合成掺杂型硫氧化镧(La2O2S)。

特点和优势

  • 热稳定性
  • 低毒
  • 反应条件温和
  • 化学选择性
  • 低成本
