But there are some exceptions: ninhydrin comes to mind. Also acetone-water mixtures have a small amount of 2,2-propanediol (acetone hydrate) by the equilibrium (CH3)2CO + H2O == (CH3)2C(OH)2. --David Shobe, Ph.D., M.L.S.

Some references are appreciated as I have found only a few articles on this kind of compound. Best Regards Kevin --------------------------------- New Yahoo! Messenger with Voice.

Hi CCLers,
I am working on a compound which has two hydroxyl groups on the same secondary carbon atom (not primary),
might someone inform me about the stability of a dihydroxyl compound and its synthetic reliability (I mean is a compound like this stable?).
Some references are appreciated as I have found only a few articles on this kind of compound.
 
Best Regards
 
Kevin
