Abstract
2,6-Di-tert-butyl-1,4-benzoquinone (1) reacts with phosphorus ylides to give alkyl 1-p-hydroxyarylfumarates (ca. 75%); triethyl/methyl phosphites react with 1 and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ, 4) on oxygen but triisopropyl phosphite reacts with 1 on oxygen and with 4 on carbon.
