A method for the production of alkyne carboxylic acids and alkyne carboxylic acid - alkyne alcohol esters by oxidation of alkyne alcohols

摘要

The invention relates to a method for the production of alkyne carboxylic acids and alkyne carboxylic acid - alkyne alcohol esters, characterized by the oxidation of an alkyne alcohol with 1 to 10 mol of - equivalent of a hypohalogenite, based on the number to an oxidizing functional groups in the presence of a nitroxyl compound at a ph - value of less than 7 or characterized by the partial oxidation of the alkyne alcohol with 0,5 to 5 mol of - equivalent of a hypohalogenite, based on the number to an oxidizing functional groups in the presence of a nitroxyl compound at a ph - value of less than 7.
