摘要:
The present invention relates to a process for preparing unsymmetrical secondary tert-butylamines which, in addition to the tert-butyl radical, also contain an alkyl, cycloalkyl or benzyl radical. They are prepared by reacting corresponding aldehydes with tert-butylamine and hydrogen in the presence of hydrogenation catalysts (reductive amination) in the liquid phase.
