To complement the the Organic Reaction Map posted a week or so ago, here’s a reaction map looking at reactions that allow you to vary the substituents on a benzene ring. This was a far larger undertaking than expected; the bulk of the work on the organic reaction map was done in the space of a day, whereas this one is probably pushing towards three days – suffice to say that there were a lot of reactions that could’ve been included!
As far as the content goes, this map (hopefully) details the majority of basic reactions of aromatic compounds. It certainly includes all the reactions necessary for most A Level courses, and more besides. The many possible reactions, and the fact that I really don’t like arrows crossing over in a tangled mess if I can help it, means that it’s by no means exhaustive, but it should be conclusive enough for casual reference purposes.
If you’re also a chemist and can spot something horribly wrong, then please let me know – similarly if you have any suggestions for something you think should have been included but hasn’t.
