General description

Pentafluorophenyl isocyanate (PFPI), an aryl isocyanate, is an N-protecting reagent. The photoinduced intermolecular carbamoylation of tertiary ethereal C-H bond of fused bicyclic system using PFPI/benzophenone has been reported. Reacting wood polymers with PFPI can make them resistant to fungal attack by forming a stable carbamate bond.

Application

Pentafluorophenyl isocyanate may be used in the preparation of:
  • pentafluorophenyl end-capped poly(ethylene glycol) (PF-PEG-PF)
  • 9-O-(pentafluorophenylcarbamoyl)quinine
  • 9-O-(tert-butyldimethylsilyl)-10-(pentafluorophenylcarbamoyloxy)-6′-methoxy-11-norcinchonan-9-ol
  • substituted 2,6-ethynylpyridine bisphenylurea scaffolds
  • novel O-xylyl bridged hexaurea receptor for atmospheric CO2 uptake
