Desulfonylative Electrocarboxylation with Carbon Dioxide

Electrocarboxylation of organic halides is one of the most investigated electrochemical approaches for converting thermodynamically inert carbon dioxide (CO2) into value-added carboxylic acids. By converting organic halides into their sulfone derivatives, we have developed a highly efficient electrochemical desulfonylative carboxylation protocol. Such a strategy takes advantage of CO2as the abundant C1 building block for the facile preparation of multifunctionalized carboxylic acids, including the nonsteroidal anti-inflammatory drug ibuprofen, under mild reaction conditions.

Preparation method of fluorophenylacetic acid

The invention relates to the field of chemical synthesis, and particularly relates to a preparation method of fluorophenylacetic acid. The invention provides a preparation method of fluorophenylacetic acid. The preparation method comprises the following steps: diazotization addition reaction: enabling a compound of the formula II to react in a system containing vinylidene chloride, acid, a diazonino reagent, a phase transfer catalyst and a copper catalyst to produce a compound of the formula III; and hydrolysis reaction: hydrolyzing the compound of the formula III to produce a compound of the formula I under the existence condition of acid. The preparation method is simply and easily available in raw materials, simple and convenient to operate, low in raw material cost, mild in reaction conditions, and low in danger, free from the use of high-price noble metal catalyst and complicated industrial operation means, and the quality of the product is stable, and therefore, the preparation method is suitable for industrial large-scale production.
