Electrophilic aromatic substitution - Wikipedia

WebIn electrophilic aromatic substitutions, a benzene is attacked by an electrophile which results in substition of hydrogens. However, halogens are not electrophillic enough to break the aromaticity of benzenes, which require a catalyst (such as FeCl 3) to activate. See above for a detailed examination of the mechanism for bromination of benzene. Web26 feb. 2015 · The A protons nicely reflect the ortho-para direction since they haven't shifted from benzene's 7.26 ppm signal and the B and C protons are all upfield as expected. Also I don't think steric hindrance is a big factor either since aromatic electrophilic substitution goes first trough a $\pi$-intermediate and a single methyl-group is not that bulky. paediasure neutral
