These compounds are commonly used as complements for quaternary ammonium salts in phase transfer catalysis.
These compounds are commonly used as complements for quaternary ammonium salts in phase transfer catalysis. Initially synthesized by the linking of hydroxyl groups on multiple catecholes by Pedersen, these compounds have a naming scheme in which the number of ring atoms is followed by their common name, which is followed in turn by the number of oxygens. The Aza- form of these molecules has an amine group displacing an oxygen as exemplified by cyclen. These heterocyclic ring compounds are comprised of several residues having general formula R O R-prime. For ten points, name these molecules that are best known for their ability to stably complex metal cations in their centers and that are comprised of several ethers.
