Quinone methides are a class of conjugated organic compounds that contain a cyclohexadiene with a carbonyl and an exocyclic methylene group (a double bonded carbon). The carbonyl and methylene are usually oriented either ortho or para to each other (there are some examples of transient synthetic meta quinone methides). The two simplest examples of this class of compounds are pictured below.
