Application

Tris(dimethylamino)phosphine can be used a reagent in combination with CCl4 for the conversion of hydroxyl groups to the corresponding chlorides; for hydroxyl group activation; dehydrations.
Tris(dimethylamino)phosphine can be used as a:
  • Ligand in the preparation of arene-ruthenium(II) complex which is used as a catalyst in hydration of nitriles to amides.
  • Phosphorus source along with InCl3 in the synthesis of InP colloidal quantum dots (QDs).
  • Deoxygenating agent for some α-dicarbonyl compounds in the presence of fullerene C60.

The reactions of such cyclic α-diketones as acenaphthenequinone, aceanthrenequinone, and N-alkylisatins, with hexaethyltriaminophosphine in the presence of the fullerene C(60), lead to the formation of methanofullerene derivatives under mild conditions. This process proceeds via deoxygenation of the dicarbonyl compound by
