CCL: Dihydroxyl compound



 Sent to CCL by: "Shobe, David" [dshobe{=}sud-chemieinc.com]
 Normally secondary gem-dihydroxy compounds (ketone hydrates) are not stable,
 even less so than primary gem-dihydroxy compounds (aldehyde hydrates).
 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.

 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
