General description

Dibenzo-24-crown-8 is a macrocyclic compound that is used as a versatile reagent in organic synthesis due to its ability to form complexes with metal ions and enhance their solubility and reactivity. It is also used as a phase-transfer catalyst in various organic reactions, such as the synthesis of organic carbonates and the alkylation of phenols.

Application

Dibenzo-24-crown-8 can be used as a molecular transporter in the formation of [1]rotaxanes with thiazolium-based mono- and tris-branched ammonium ions. It is also used as a co-solvent and phase-transfer catalyst for cesium fluoride, to the development of a more efficient anhydrous fluorinating system for organic synthesis.
