Description

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.
