Chemical Properties
violet-black monoclinic crystal(s) [CRC10]
Uses
NIOBIUMCHLORIDE is used as reductively couples imines and nitriles.
Preparation
Reduction 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.
