It is analogous to a quinone, but having one of the double bonded oxygens replaced with a carbon. The carbonyl and methylidene are usually … See more Quinone methides are cross-conjugated rather than aromatic. Nucleophilic addition at the exo-cyclic double bond will result in rearomatisation, making such reactions highly favourable. As a result, quinone methides are … See more Quinones methides are commonly invoked in biochemistry, but are rarely observed as long-lived intermediates. Biosynthesis of dehydroglycine Quinone methide itself arises by the degradation of tyrosine, leading ultimately to p- See more • Formation and Stability of Simple Quinone Methides • Quinone methide intermediates in organic Photochemistry See more Quinone methides are often prepared by oxidation of the corresponding ortho or para cresol. Quinone methides … See more A quinone dimethide (or "xylylene") is a compound with the formula C6H4(=CH2)2. Thus they are related to quinone monomethides (the … See more flyfiretech
