Niobium(V) chloride

It is used to form mixed chloro-aryloxide compounds, such as [Nb(OC6H3-2,6-i-Pr2)2Cl3]2, which form pyridine or phosphine adducts with a distorted six-coordinate geometry. It is also used in the preparation of pure niobium, and as an intermediate, precursor to many other laboratory reagents.

Niobium(V) chloride

Niobium(V) chloride is a chemical compound that is used as a catalyst in organic reactions. It is an ionic salt of niobium pentachloride and hydrochloric acid, with the formula NbCl5·HCl. Niobium(V) chloride is a solid, which can be obtained as a white powder or crystalline solid. The structural properties of this compound have been studied using x-ray crystallography and FTIR spectroscopy. Niobium(V) chloride reacts with acyl chlorides or esters to form ester or amide derivatives, respectively. This reaction proceeds via an acylation reaction mechanism involving nucleophilic substitution at the carbonyl carbon atom of the acyl chloride or ester reactant by the chloride ion in niobium(V) chloride. Niobium(V) chloride has also been shown to catalyze hydrogen fluoride and hydrochloric acid reactions, which may be due to its
