Abstract

Benzene rings can be found in about 30% of all industrial chemicals and in over half of the top 50 drugs.[1] This fact clearly illustrates the immense scientific and commercial value of aromatic compounds in modern society. These compounds usually bear more than one substituent on the benzene ring, and are traditionally constructed by the stepwise introduction of substituents through electrophilic aromatic substitution (Scheme 1a). ...
