From wikipedia:
| Quote: |
CrCl2 is produced by reducing chromium(III) chloride with hydrogen at 500 °C:[1]
2 CrCl3 + H2 → 2 CrCl2 + 2 HCl
Small scale preparations can use LiAlH4, or related reagents, to reduce CrCl3
4 CrCl3 + LiAlH4 → 4 CrCl2 + LiCl + AlCl3 + 2 H2
Commonly, it is generated by reduction of CrCl3 with zinc.
2 CrCl3 + Zn → 2 CrCl2 + ZnCl2

Any of those sound accessible for you?
