本文描述了一种用层状双氢氧化物负载的金（LDH-AUCl（4））催化剂，使醛、胺和炔三组分偶联，以几乎定量的产率生成炔丙胺。芳香族和脂肪族醛和胺都用于该反应。不需要额外的助催化剂或活化剂。
A three-component coupling of aldehydes, amines and an alkyne to generate propargylic amines in nearly quantitative yields, using a layered double hydroxide-supported gold (LDH-AUCl(4)) catalyst is described. Both aromatic and aliphatic aldehydes and amines are used for the reaction. No additional co-catalyst or activator is required.
