Beschreibung

Anwendung

Selenourea [(SeC(NH₂)₂)] has been used as a selenium (Se) precursor for the insertion of Se into protein crystals.
It can also be used as a reagent to synthesize:

• Selenazoles from α -bromo ketones presence of β -cyclodextrin.
• Symmetrical diaryl selenides by C-Se cross coupling reaction in presence of coper oxide nanaoparticles as a catalyst.
• CdSe nanocrystals.
