Vanadium (V) oxide trifluoride is an inorganic chemical compound of vanadium from the group of oxide fluorides .

Extraction and presentation

Vanadium (V) oxide trifluoride can be obtained by reacting vanadium (III) fluoride with oxygen .

{\ displaystyle \ mathrm {2 \ VF_ {3} + O_ {2} \ longrightarrow 2 \ VOF_ {3}}}

It is also produced by hydrolysis of vanadium (V) fluoride .

{\ displaystyle \ mathrm {VF_ {5} + H_ {2} O \ longrightarrow VOF_ {3} +2 \ HF}}

properties

Vanadium (V) oxide trifluoride is a light yellow moisture-sensitive solid. It has an orthorhombic crystal structure with the space group Pnma (space group no. 62) . With water it hydrolyzes to vanadium (V) oxide hydrate. Template: room group / 62

{\ displaystyle \ mathrm {2 \ VOF_ {3} +3 \ H_ {2} O \ longrightarrow V_ {2} O_ {5} \ cdot H_ {2} O + 6 \ HF}}

use

Vanadium (V) oxide trifluoride is used in organic synthesis for the oxidative coupling of phenol rings , for example for the production of vancomycin .
