Elimination is preferred with increasing leaving tendency of the halides (I > Br > > Cl > > F) and with decreasing reactivity of the carbonyl compounds. Exclusive elimination to 1,2-didehydrobenzenes - which are trapped with furans - occurs in the reaction when no electrophiles are present.deinfo:eu-repo/semantics/openAccessEliminierungsreaktion , Halogenbenzole540Zur Reaktion von Halogen(trimethylsilyl)benzolen mit Elektrophilen und Basen : Carbodesilylierung und Eliminierung als KonkurrenzreaktionenReaction of halo(trimethylsilyl)benzenes with electrophiles and bases : carbodesilylation and elimination as competitive reactionsarticle2010-01-20
