Application

Benzyltriphenylphosphonium chloride can be used as a reactant for the synthesis of:
  • Platinum chloro-tetrazole complexes via azidation.
  • Trans-stilbenes and cinnamates via Wittig olefination.
  • Achiral N-hydroxyformamide inhibitors of ADAM-TS4 and ADAM-TS5 for osteoarthritis treatment.
  • Pentiptycenes for use as light-driven molecular brakes.
  • Archipelago structures for formation of petroleum asphaltenes.


It is also used as a crosslinking agent for tube-like natural halloysite / fluorelastomer nanocomposites.
