[2] Types of carbocyclic arene dearomization include hydrogenative (Birch reduction), alkylative, photochemical, thermal, oxidative, transition metal-assisted and enzymatic.
[1] Examples of photochemical reactions are those between certain arenes and alkenes forming [2+2] and [2+4] cycloaddition adducts.
[1] Examples of enzymes capable of arene dearomatization [3][4] are toluene dixoyhydrogenase, naphthalene dixoyhydrogenase and benzoyl CoA reductase.
[1] A classic example of transition metal-assisted dearomatization is the Buchner ring expansion.
[1] Catalytic asymmetric dearomatization reactions (CADA) are used in enantioselective synthesis.
