Fluoride-induced 1,2-elimination of o-trimethylsilylphenyl triflate provided a convenient route to benzyne under mild conditions where detriflation from an intermediary aryl anion appeared to occur in preference to protonation even in the presence of alcohols.
Das aus dem Silylether (I) zugängliche Triflat (II) wird durch die Fluoride (III) in Dehydrobenzol (IV) übergeführt, das mit Furan (V) zum Addukt (VI) und mit den Alkoholen (VII) zu den Phenolethern (VIII) weiterreagiert.
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.
