A rapid and productive vicinal diamination of alkenes takes place in the presence of a hypervalent iodine(III) reagent and bissulfonimides as nitrogen sources. A total of more than 60 examples are presented. The reaction is characterized by its robustness and its wide substrate scope: it proceeds selectively with both terminal and internal alkenes and tolerates a range of functional groups.

New dinuclear iodine(III) reagents for the intermoleculardiamination of alkenes are reported. These are accessible through protolytic aminolysis events, which generate defined imido-iodine(III) groups.

Only I and N: Hypervalent iodine(III) reagents with two reactive IN single bonds have been isolated for the first time. Their solid‐state and solution structures provide evidence for enhanced electrophilicity at iodine and nucleophilic character of the imine. As a result, improved reactivity in amination reactions and unprecedented nitrogen‐transfer reactions under metal‐free conditions are realized
sources and 3‐chloroperbenzoic acid (mCPBA) as benign terminal oxidant they catalyze the vicinal diamination of styrenes. The obtained reactivity and selectivity outperform other iodoarene catalyst candidates. This protocol provides a sustainable alternative to previous related protocols for diamination that are based on stoichiometric iodine(III) reagents.
