Application

Tris(trimethylsilyl)phosphine (P(TMS)3) can be used as a precursor for the syntheses of:
  • Indium phosphide (InP) and indium gallium phosphide (InGaP) nanocrystals, type III-V semiconductors.
  • Chiral TMS-phospholane which can be further used to synthesize various bisphospholane ligands for asymmetric catalysis.
