Applicazioni

Tris(diethylamino)phosphine [(Et2N)3P] can be used as a reagent to synthesize:
  • 1,1′-Dialkylisoindigo derivatives by reacting with various 1-alkylisatins via deoxygenation reaction.
  • 1-Aminomethylisatins by treating with isatin and primary and secondary amines.

It can also be used in the deoxygenation of some cyclic α-diketones using fullerene C60.

Multiple exciton generation (MEG) is a process in which more than one exciton is generated upon the absorption of a high energy photon, typically higher than two times the band gap, in semiconductor nanocrystals. It can be observed experimentally using

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
