Uses
Vanadium dichloride (CAS NO.10580-52-6) is a powerful reducing species, being able to reduce sulfoxides to sulfides, organic azides to amines, as well as reductively coupling some alkyl halides. Some derivatives have been shown to reduce nitrogen to hydrazine and ammonia.
Production
Vanadium dichloride (CAS NO.10580-52-6) is prepared by thermal decomposition of VCl3 to volatile VCl4, leaving a residue of VCl2.
