ABSTRACT:
The liquid-phase catalytic hydrogenation of N-acetoacetyl arylamides to yield 3-hydroxybutyric acid arylamides proceeds much faster when amines, phosphines or trialkylphosphates are added. Thus, even with lower hydrogen pressures and at lower temperatures with a lower catalyst concentration, shorter reaction times are sufficient.
