| Product | 4,4'-Dimethylbenzophenone | HCID 69148 | 60.9% |
Reaction Steps
Cerium(III) trifluoromethanesulfonate (3.23 g as a wet solid) and para-toluic acid (1.36 g) were refluxed together in 125 mL toluene as in Example 3, but for 48 hours., After work-up (as in Example 3) crude 4,4′-dimethylbenzophenone (0.64 g, 30% yield) was obtained as a cream-colored crystalline solid.
