The secondary α-deuterium isotope effect on the equilibrium constant (KD/KH) for the hydration of p-nitrobenzaldehyde is 1.39 +/- 0.05.The kinetic secondary α-deuterium isotope effect (kD/kH) for the addition of water to p-nitrobenzaldehyde is 1.18+/-0.07.This result demonstrates that there is extensive carbon-oxygen bond formation in the transition state for addition of water to the carbonyl group of p-nitrobenzaldehyde.
