NIOBIUMCHLORIDE Usage And Synthesis
Chemical PropertiesBrown-black crystal needles; pure brown in transmitted light.
Decomposes on exposure to air and moisture (color change first to black, then to white). Dissolves in a small amount of H2O and in dilute hydrochloric acid, giving a dark-blue solution.
Uses NIOBIUMCHLORIDE is used as reductively couples imines and nitriles.
PreparationReduction of NbCl5 with H2 at 2 atm. (generated when the tube is filled at STP, sealed and then heated). The reaction does not go to completion and NbCl5 and NbCl4 must be separated by sublimation.
Purification Methods NIOBIUMCHLORIDE is Purified by filter and wash with THF and dry under vacuum.
Precautions Niobiumchloride is corrosive; moisture sensitive. Use in a fume hood.
