Copper-aluminium hydrotalcite (CuAl-HT)/K2CO3 has been employed in the activation of various benzyl alcohols with benzylamines to afford the corresponding amines in good to high yields. Experimentation showed that the reaction takes place through sequential transformations: the oxidation of alcohols into carbonyl compounds, imine formation between amines and carbonyl compounds, and then reduction ofimines
铜铝水滑石 (CuAl-HT)/K2CO3 已用于用苄胺活化各种苄醇,以良好或高产率提供相应的胺。实验表明,该反应通过顺序转化进行:醇氧化为羰基化合物,胺和羰基化合物之间形成亚胺,然后亚胺还原为胺,由非贵金属 Cu-Al HT 催化剂在一锅中多相催化和简单的时尚。该过程进一步扩展到醇与苯胺的胺化,苯胺在被强吸电子基团取代时通常对烷基化反应具有抵抗力。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
