Process for preparing alkynecarboxylic acids by oxidation of alkyne alcohols

A process for preparing alkynecarboxylic acids includes the oxidation of an alkyne alcohol with a hypohalite in the presence of a nitroxyl compound at a pH of greater than 7 with continual addition of the alkyne alcohol and of the hypohalite to the reaction mixture.

Catalyzed oxidation of alcohols by cis-dioxomolybdenum(VI) complexes via oxygen atom transfer from sulfoxidest

Catalytic amounts of cis-dioxomolybdenum(VI) complexes in association with sulfoxides can be used to oxidize alcohols into carbonyl compounds. For primary alcohols, the oxidation into aldehyde is selective, no further oxidation into carboxylic acid is observed. The oxidation is most effective for benzylic and allylic alcohols. The mechanism is shown not to be of a Swern-type Me2SO oxidation but probably involves a hydride transfer from a coordinated alkoxide to an oxo ligand on the Mo(VI) thereby forming aldehyde and an Mo(IV) species, the latter being reoxidized to Mo(VI) by the sulfoxide in an oxygen atom transfer step.

Cis-dioxomolybdenum(VI) complexes as new catalysts for the Meyer-Schuster rearrangement

We describe a new catalytic system for the isomerisation of propargylic alcohols into α,β-ethylenic carbonyl derivatives (Meyer-Schuster rearrangement), based on the combination of dioxomolybdenum(IV) catalysts and sulfoxides.
