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

A series of sixteen bisphenylureas based on a 2,6-bis(2-anilinoethynyl)pyridine scaffold have been synthesized for use as potential anion sensors. Prior work with one of these receptors revealed a distinct fluorescence response in the presence of a suitable anion source with

A new hexaurea receptor has been synthesized, which absorbs atmospheric CO2 to produce an air-stable solid carbonate complex under normal conditions. Structural analysis of the carbonate complex with this receptor suggests that the carbonate is fully encapsulated within its highly
