pected in the Leuckart reaction if formamideit- self were used rather than ammonium formate, benzophenone was refluxed with 99% formamide; after refluxing. Preparation of Aliphatic Amines by the Leuckart Reaction. Lin Yang, Rongji Dai, Wei Liu, and Yulin Deng. School of Life Science and Technology, Beijing. This reaction is the reductive amination of carbonyl compounds (i.e., or tertiary amines and is generally known as the Leuckart reaction.
