The number of applications that use halogen bonding in the fields of self-assembly,
supramolecular aggregation, and catalysis is growing. However, the accessibility of
chiral halotriazoles shows that there is still a lot more to explore. The simple click-chemistry
is applied for the straightforward synthesis of enantiomerically pure mono- and bidentate
as well as multifunctional iodotriazole-based XB donors. The methodology is characterized
by a wide variability due to easy access of chiral azides.
