The Mechanism of the Mitsunobu Azide Modification and the Effect of Additives on the Rate of Hydroxyl Group Activation

The Mitsunobu azide modification has been studied by NMR using a hindered alcohol and the principle intermediates involved have been tentatively identified.The accelerated hydroxyl group activation in the presence of hydrazoic acid or of catalytic quantities of phenol gives us an insight into the reactivity of some of the intermediates involved in these reactions.
