propylene glycol oxidation


via routes described elsewhere on the site, could one synthesize 2-hydroxy-propionaldehyde?

what would a metal-catalyzed oxidation do (i.e. pt-pyrdine complex)?

I'm stupid :)

here's a somewhat applicable source, however I am not interested in metallurgy and doping molybdenum into iron :|

I am guessing the yields would be very poor. The central hyroxy group (in the 2-position) is more vulnerable to oxidation than side hydroxy group. And yields for obtaining aldehydes by oxidation of alcohols are typically very low, since aldehydes are much more vulnerable to oxidation than the initial alcohol.

There may be regents/catalysts that could selectively oxidize propylene glycol to CH3-CH2(OH)-CH=O, without (or with only minimal) formation of undesirable hydroxyacetone.
