Application

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.

We report a general strategy for obtaining high-quality, large-area metal-chalcogenide semiconductor films from precursors combining chelated metal salts with chalcoureas or chalcoamides. Using conventional organic solvents, such precursors enable the expeditious formation of chalco-gels, which are easily transformed into the
