• The alkaline peroxide oxidation of 1′,2′-dihydroxy-3,4-benzotropolones
  作者：P. D. Collier

  DOI：10.1039/j39690000612

  日期：——

  The alkaline peroxide oxidation of 1′,2′-dihydroxy-3,4-benzotropolones proceeds via the corresponding 1′,2′-quinone anions, which undergo two types of peroxide decomposition. (a) At low temperature and alkali concentration, peroxide attack on the 3′- and 4′-positions of the cyclohexadiene ring predominates, and results in the formation of unstable hydroperoxides which decompose to hydroxyquinones,

  1'，2'-二羟基-3,4-苯并呋喃酮的碱性过氧化物氧化反应通过相应的1'，2'-醌阴离子进行，该阴离子经历两种类型的过氧化物分解。（a）在低温和碱浓度下，过氧化物主要侵害环己二烯环的3'-和4'-位，并导致形成不稳定的氢过氧化物，其分解为羟基醌，这也直接通过溶剂分解而形成。3'-位的更高反应性归因于其与醌型和托酚酮羰基的共轭。由3'-取代的底物形成的2'-羟基-1'，4'-醌被进一步氧化为托酚酮-3,4-二羧酸酐。（b）在高温和碱浓度下会形成粘康酸通过过氧化氢引起的四羟基苯并呋喃酮和二羟基-2'，6'-醌类酮类化合物对tro环酮环的5位，6位和7位进行攻击。当底物在6-位带有羧基时，不会形成这些四羟基苯甲酮（也可通过水解1'，2'-醌的异常Thiele五乙酸酯获得）；在这种情况下，过氧化物对环己二烯环的1'-和2'-位的侵蚀占主导地位。
