✦ Synopsis

In order to bring more information on the thermodynamic and kinetic behavior of nitryl chloride in aprotic media, we have surveyed exhaustively the first NO2C1reduction step in sulfolane (at the platinum electrode), taking into account our preliminary results about the electrochemical properties of NOzCl in aprotic solvents. We have excluded the intervention of the weak ionic dissociation of NOzCl (NOZC1 NOz' + C1-[I]) and its slow molecular decomposition as: 2N02C1 ClZ + 2NO; (e N204) [I13 in this process. We have admitted the occurrence of a rapid chemical reaction which controls kinetically the electrochemical system studied: NO + NOzCl 4 NOCl + NO; [III].

By analyzing the kinetic currents resulting from the 1st cathodic wave of NOzCl at the temperature range 303-323 K, the rate constant, k*, and the activation energy, E*, of reaction [III] have been determined. These results and those previously found in the gas phase are discussed.

This review deals with two of the most commonly used methods for the preparation of amines: the reductive amination of aldehydes and ketones and the hydrogenation of nitriles. There is a great similarity between these two methods, since both have the imine as intermediate. However, due to the high r
