Abstract

The steady state initla1 rate equation for a ketone-ethanol-NAD+-HLAD recycling system is checked for 1-n-butyl-4-piperidone. All reaction parameters are discussed in order to optimize the reduction of this substrate. For a series of 1-alkyl-4-piperidones the thermodynamic activation parameters for the reduction in this system are determined and discussed.
