    摘要： An object of the present invention is to provide a novel method for producing an α-fluoroacrylic acid ester compound. This problem is solved by a method for producing a compound represented by formula (1), wherein R1 and R2 are identical or different, and each represents an alkyl group or the like; and R3 is an alkyl group or the like, the method comprising step A of reacting a compound represented by formula (2) with R3—OH (3) and carbon monoxide in the presence of palladium, a double bond-containing compound (α), a diphosphine compound (β), and a base, to obtain the compound represented by formula (1) above.

    摘要： An integrated process for the preparation of carboxylic acids using iso-paraffins is provided. The process includes oxidatively carbonylating a compound having a carbon-hydrogen bond with dialkyl peroxide, carbon monoxide and water. Concurrently, the iso-paraffin is converted to iso-alcohol. The process provides access to a wide range of useful carboxylic acids and operates under relatively mild conditions.
