The stereospecific, substrate (nitrogen source)-controlled intermolecular anti- and syn-1,2-diaminations of unactivated alkenes using the same catalysis (an iodine catalyst) is reported. The combined use of the two potential methods provides access to all of the disastereomeric forms of 1,2-diamines in spite of the availability of E- and Z-alkenes, and the resulting products can be readily converted

synthetically valuable nitrogen‐containing building blocks which are difficult to obtain with alternative methods. Preliminary mechanisticstudies suggest that the reaction may proceed through a new mechanistic pathway in which both Lewisacid activation and iron‐enabled redox‐catalysis are crucial for selective azido‐group transfer.
