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.
