A re-examination of the methylenation reaction of 1-hydroxy-2-mercapto-, 1,2-dihydroxy- and 1,2-dimercapto-substituted benzenes by bromochloromethane with cesium carbonate shows that these substrates give mixtures of five- and ten-membered benzocondensed heterocyclic compounds and in some cases even dibenzodioxines.
溴氯甲烷与碳酸铯对1-羟基-2-巯基,1,2-二羟基和1,2-二巯基取代的苯的甲基化反应的重新检查表明,这些底物会生成五和十的混合物元的苯并稠合的杂环化合物,在某些情况下甚至是二苯并二恶英。
