  摘要：

  The Penicillium frequentans strain Bi 7/2, using phenol as a sole source of carbon and energy, transformed the fluorinated phenols 2,3-, 2,4-, 2,5- and 3,4-difluorophenol rapidly. After growth on phenol, resting mycelia of the fungus converted the difluorophenols completely at an initial concentration of 0.5 mM within 6 hours. The corresponding difluorinated catechols were found to be intermediates of all difluorophenols investigated. A relatively unspecific phenol hydroxylase catalyzed this hydroxylation step and showed activities towards all difluorophenols tested. One difluorocatechol was formed from each difluorophenol substituted with fluorine in the ortho-position, whereas two catechols were formed from 3,4-difluorophenol, due to its two vacant ortho-positions. A partial defluorination (50-77%) was observed in all cases.

• Selective<i>Ortho</i>-Hydroxylation-Defluorination of 2-Fluorophenolates with a Bis(μ-oxo)dicopper(III) Species

  The bis(μ‐oxo)dicopper(III) species [CuIII2(μ‐O)2(m‐XYLMeAN)]2+ (1) promotes the electrophilic ortho‐hydroxylation–defluorination of 2‐fluorophenolates to give the corresponding catechols, a reaction that is not accomplishable with a (η2:η2‐O2)dicopper(II) complex. Isotopic labeling studies show that the incoming oxygen atom originates from the bis(μ‐oxo) unit. Ortho‐hydroxylation–defluorination occurs
