Organoiodine-mediated Dehydrogenative N–N Coupling of Aryl Alkoxycarbamates

An environmentally benign and efficient approach has been developed for the construction of corresponding N–N coupled dialkoxyhydrazines in good yields (up to 91%) via phenyliodine diacetate (PIDA) mediated oxidative dimerization of alkoxycarbamates. The advantages of this transformations are mild conditions, functional-group tolerance and operationally simple. Notably, the cross-coupling of two different aryl alkoxycarbamates is also demonstrated, which provides a straightforward method to structurally complex N–N molecules.
