The reaction of 1-propyl-1,4-dihydronicotinamide with hexacyanoferrate(III) in 20% aqueous methanol follows a second-order rate law with first order with respect to each reactant concentration. Kinetic parameters are <I>ΔH</I><SUP>\neweq</SUP>: (8.8±0.4)×10<SUP>3</SUP> J mol<SUP>−1</SUP> and <I>ΔS</I><SUP>\neweq</SUP>: −1.8×10<SUP>2</SUP> J mol<SUP>−1</SUP> K<SUP>−1</SUP>, the observed kinetic isotope effect, <I>k</I><SUB>H</SUB>/<I>k</I><SUB>D</SUB>, being 1.51. The mechanism of the reaction is discussed.
