Procedure

Chromium (VI) oxide (48 g, 0.48 mol) was dissolved in 6M HCl (88 mL, 0.53 mol) at 40° C. to form an orange solution. (See FIG. 17). The solution was then cooled to 10° C., and pyridine (38.8 mL, 0.48 mol) was added to the solution. A yellow orange precipitate was slowly formed. After the solution was heated to 40° C., the precipitate was dissolved. Aluminum oxide basic (380 g, 3.73 mol) was added to the solution, and the mixture was stirred well with a stir rod. The resulting solid was dried under vacuum and stored under argon atmosphere.
