Jon,
Thanks to Jacobo and Jon for your advices. I thought about changing solvent, but the problem is the solubility of DMP in CCl4, and CHCl2 was used as the solvent in most of the papers. --I'm not going to use hexane, because it won't dissovle my sample.
The ratio of enol to ketone is not reproducable, and it seems not depend on the quantity of DMP either. The DMP in our group works very well to the other system. So, I guess the only problem is my compound. Unfortunately, I can not change anything on the molecule, even though there's a good method used in Tetrahedron 2003, 59, 2929.
Anyway, I'm gonna try it in CCl4. If it fails, I have to use the other oxidant.
