Eas reactivity
WebIn this tutorial I want to talk about the electrophilic aromatic substitution (EAS) reactions. The EAS reactions are one of the fundamental and unique reactions of aromatic … WebThe high reactivity of anisole, for example, requires that the first two reactions be conducted under very mild conditions (low temperature and little or no catalyst). The nitrobenzene reactant in the third example is very unreactive, so rather harsh reaction conditions must be used to accomplish that reaction.
