Description

Description générale

Benzo-15-crown-5 is a macrocyclic compound that belongs to the class of crown ethers. It is used as a ligand in metal-catalyzed reactions to enhance the reactivity and selectivity by coordinating with metal cations. For instance, it has been utilized in certain metal-catalyzed cross-coupling reactions, such as Suzuki-Miyaura or Stille reactions, to improve the efficiency and selectivity of the transformations. Benzo-15-crown is also employed as a phase-transfer catalyst in organic synthesis.

Application

Benzo-15-crown-5 can be used as a reactant in the synthesis of a phenol-based benzo-15-crown-5 ether resin. The resulting resin further used for lithium isotope separation, which relies on the selective absorption of the Li-6 isotope.
