In the present investigation, we have measured the secondary kinetic deuterium isotope effects in hydroxylamine addition reaction for a series of cyclohexanones, both hindered and unhindered. We observed a slightly direct isotope effect, __k__^H^__/k__^D^ > 1.00, for unhindered cyclohexanones and an

The effect of self-association on the carbonyl carbon NMR screening constant is determined for 15 ketones. It is shown that the corresponding screening constant term can only be related to the dipole moment and the molecular volume both for aliphatic and alicyclic ketones. The average distance betwe

## Abstract The rates of racemisation, under constant conditions of pH and temperature, of two series of ketones with an asymmetric C‐atom in α have been determined. As would be expected, substituents in the α position to the keto group influence the rate of racemisation, and it has been found poss
