• Properties of chlorinated dihydroxybenzenes — Components of pulp bleaching effluents
  作者：Terrence J. Smith、Ross H. Wearne、Adrian F.A. Wallis

  DOI：10.1016/0045-6535(94)90285-2

  日期：1994.10

  Gas chromatography and mass spectrometry data are given for the acetates of the chlorodihydroxybenzenes which are components of wood pulp bleaching effluents and biologically-treated effluents, and are proposed intermediates in the chlorination of humic acids. The chlorohydroxybenzenes include the nine chlorocatechols, the six chlorohydroquinones and the seven known chlororesorcinols. The 22 chlorinated compounds were generally well separated on a phenyl methyl silicone column with the exception of three dichloro compounds. The chloro compounds with the same level of chlorine substitution were not able to be distinguished on the basis of their electron impact mass spectra.
• Synthesis of Catechols from Phenols via Pd-Catalyzed Silanol-Directed C–H Oxygenation

  A silanol-directed, Pd-catalyzed C-H oxygenation of phenols into catechols is presented. This method is highly site selective and general, as it allows for oxygenation of not only electron-neutral but also electron-poor phenols. This method operates via a silanol-directed acetoxylation, followed by a subsequent acid-catalyzed cyclization reaction into a cyclic silicon protected catechol, A routine desilylation of the silacyle With TBAF uncovers the catechol product:
