Ring Contraction of Some Dialkylamino‐ and Methoxy‐substituted 1,2‐ and 1,4‐Benzoquinones The dialkylamino and methoxy‐substituted 1,2 and 1,4‐benzoquinones 1a, b, 4, 6 , and 8 react with sodium metaperiodate in methanol/water to give the ring‐contracted products 3a, b, 5, 7 , and 9 . Compound 3b is also obtained by the reaction of 1b with 3‐chloroperoxybenzoic acid.
