Catalytic oxidations of alkynes by dilute hydrogen peroxide are performed in dioxane and in a two phase dichloroethane/water system utilizing sodium molybdate or tungstate salts in the presence of mercuric acetate or trifluoroacetate. Internal alkynes display low reactivity in both solvent systems, whereas terminal alkynes are fast oxidized in the two phase system. One less carbon atom carboxylic acids or alpha-ketoalehydes are formed depending on the nature of the metal and of the extracting agent.

Abstract

Catalytic oxidations of alkynes by dilute hydrogen peroxide are performed in dioxane and in a two phase dichloroethane/water system utilizing sodium molybdate or tungstate salts in the presence of mercuric acetate or trifluoroacetate. Internal alkynes display low reactivity in both solvent systems, whereas terminal alkynes are fast oxidized in the two phase system. One less carbon atom carboxylic acids or alpha-ketoalehydes are formed depending on the nature of the metal and of the extracting agent.
