MECHANISM OF ALKENYLATION OF AROMATIC SUBSTRATES WITH 5-NITRO-2-FURYLVINYL BROMIDE

Hrabovsky, Jan,Kovac, Jaroslav,Povazanec, Frantisek

, p. 2013 - 2018 (2007/10/02)

Mechanism has been studied of electrophilic aromatic substitution with (Z)- and (E)-5-nitro-2-furylvinyl bromide in the presence of aluminium(III) chloride.From chemical findings and 1H NMR study it follows that the mechanism can be interpreted as an electrophilic addition-elimination pathway (AdE-E) from the point of view of the vinyl substitution.
