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.

Electrophilic reactivities of azodicarboxylates

The kinetics of the reactions of the azodicarboxylates 1 with the enamines 2 have been studied in CH3CN at 20 °C. The reactions follow a secondorder rate law and can be described by the linear free energy relationship logk2(20 °C) =
