Abstract
Bis(I2) adducts of hexamethonium dihalides are pre-organized to respond dynamically to heating and reach a functional structure that favors the formation of the poorly stable and virtually unknown [I2Br2]2− and [I2Cl2]2− tetrahalides which could not be obtained in solution (see picture). The cavity-directed reactivity affords new opportunities for synthesis and interconversion of polyhalogen anions.
