They use a simple wash with 15% hydrogen peroxide to kill the catalyst. Worried about over oxidation? The RuO2 that is formed in the process reacts with H2O2 to give H2O and O2, destroying excess peroxide in the process. There are bound to be some functional group incompatibilities, but if it's as cheap, easy, and effective as it seems, it's definitely worth a try... alchemist must have bee talking about the recent David Knight TL paper (Article in Press published Nov. 26, doi: 10.1016/j.tetlet.2009.11.092).

Are there other methods out there? This has the potential to be a convenient and inexpensive process. Are there other methods out there?

Sorry about that! Macdonald, Langmuir, 2008, 24 (14), pp 7169–7177. DOI: 10.1021/la8006734 Err, I guess it would help if I gave the reference. Sorry about that!
