Applications
Uses15-Crown-5 is used as an efficient phase transfer catalyst and as a complexing agent. It is used to isolate oxonium ion (H7O3)+ salts especially from a solution of tetrchloroauric acid. It catalyzes the O-alkylation of the sodium salts of carboxylic acids in the penicillin and cephalosporin series, thereby facilitating esterification reaction without usage of acid. It is also used to facilitate the Williamson synthesis of ethers with hindered alcohols and sodium hydride. It is used with lithium aluminum hydride, for performing reduction reactions in hydrocarbon solvents. Further, it is involved in the Horner-Wadsworth-Emmons reaction to prepare stilbenes from aldehydes.
General Description15-Crown-5 is a crown ether generally used as a ligand in coordination chemistry because of its strong chelating property with certain alkali cations to form complexes. Some derivatives of 15-crown-5 are used as sensors and probes in different physical-chemical processes, phase-transfer reactions, and selective capture of ions for separation and transport.
