Oxidation of Alkynes by Hydrogen Peroxide Catalyzed by Methylrhenium Trioxide

The oxidation of alkynes with hydrogen peroxide is catalyzed by methylrhenium tioxide.The reactions can be rationalized by postulating that an oxirene intermediate is formed between a rhenium peroxide and the alkyne.Internal alkynes yield α-diketones and carboxylic acids, the latter from the complete cleavage of the triple bonds.Rearrangement products were observed only for aliphatic alkynes.Terminal alkynes gave carboxylic acids and their derivatives and α-keto acids as the major products, but their yields varied with the solvent used.

KINETIC RELATIONS IN THE THERMODECOMPOSITION OF CALCIUM AND STRONTIUM F-SUBSTITUTED β-DIKETONATES

Kinetic relations in the thermodecomposition of calcium and strontium substituted β-diketonates (acetylacetonates, trifluoroacetylacetonates, pivaloyltrifluoroacetylacetonates, dipivaloylmethanates) and their volatilities were studied by the manometric technique under static conditions.
