Application

Tetrakis[tris(dimethylamino)phosphoranylidenamino]phosphonium chloride can be used:
  • As a lipophilic additive in the pH-responsive polymers and solvent-processible polymer membranes.
  • To prepare tetrakis[tris(dimethylamino)phosphoranylidenamino] phosphonium hydroxide, which acts as a basic catalyst for the ring-opening polymerization of siloxanes.

Other Notes

Extremely stable, lipophilic PTC; Selective O-methylation of ketone enolates
