{ALF} In the presence of NaOH, is a catalyst for the high-yield rearrangement of sec-allylic alcohols to saturated ketones: J. Chem. Soc., Chem. Commun., 594 (1980). In MeOH, allyl alcohols are converted to allyl ethers. The thermodynamically more stable isomer predominates: Synth. Commun., 12, 807 (1982):

{ALF} Used catalytically, in the presence of a suitable reoxidant, such as periodate or sometimes hypochlorite, RuCl3 is a source of the powerful oxidizing agent, ruthenium(VIII) oxide, RuO4: J. Org. Chem., 46, 3936 (1981); J. Am. Chem. Soc., 103, 464 (1981).

{ALF} Oxidations by RuO4 include: Alkenes to carboxylic acids: J. Am. Chem. Soc., 103, 464 (1981); Org. Synth. Coll., 8, 377 (1993). In biphasic solvent systems, the reaction can also be controlled to give good yields of syn-diols: Angew. Chem. Int. Ed., 33, 2312 (1994); Chem. Eur. J., 2, 50 (1996). For an improved protocol, employing only 0.5 mol% catalyst, see: Org. Lett., 5, 3353 (2003). For oxidation of diols to carboxylic acids: J. Org.
