【発明の名称】末端アルキンをカルボキシル化するための方法

Document Type and Number:

Japanese Patent JP2002506119

Kind Code:

A

Abstract:

A method for carboxylating terminal alkynes that have at least one additional aliphatic carbon atom in an alpha position and that do not have a proton which has a higher acidity than that of the proton of the terminal triple bond. In an undivided electrolysis cell equipped with a cathode and an anode, a solution of the terminal alkyne in an aprotic solvent is acted upon by carbon dioxide at a pressure higher than atmospheric pressure. The invention provides a method in which carbon dioxide is selectively inserted between the terminal C-H bond, without disturbing the triple bond, and can be carried out without a catalyst or catalyst precursor.
