Eliminations leading from enol sulfonates, enol phosphates, and enol phosphonium salts to alkynes are reviewed. Olefin eliminations are usually the rate-determining step in the formation of the triple bond. Enol esters may also play a role in the biosynthesis of alkynes.
Dieser Aufsatz gibt einen Uberblick iiber Eliminierungen, die von Enolsulfonaten, EnoE phosphaten und Enolphosphoniumsalzen zu Alkinen fiihren. Bei der Bilhng der Dreifachbindung ist gew6hnlich die Eliminierung am Olefn der geschwindigkeitsbestimmendeSchritt. Enolester k6nnen m6glicherweise auch in der Biosynthese der Alkine eine Rolle spielen.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
