Consistent with its high oxidizing power, VCl reacts with HBr at -50 °C to produce VBr.  The reaction proceeds via VBr, which releases Br during warming to room temperature.
:2 VCl + 8 HBr → 2 VBr + 8 HCl + Br
VCl forms adducts with many donor ligands, for example, VCl(THF).
It is the precursor to vanadocene dichloride.
