The first process includes the steps of (a) reacting a 2,2-bis(fluoromethyl)-6-(perfluoroalkyl)-2H-1-benzopyran-4-one with a perfluoroalkanesulfonic acid anhydride in the presence of a base, thereby obtaining a perfluoroalkanesulfonic 2,2-bis(fluoromethyl)-6-(perfluoroalkyl)-2H- 1-benzopyran-4-yl ester; and (b) reacting the benzopyranyl ester with carbon monoxide in the presence of a palladium complex compound and a base, thereby obtaining the carboxylic acid. The present invention further relates to a second process for producing a 2-hydroxy-5-(perfluoroalkyl) acetophenone, which can be a raw material for producing the carboxylic acid. The second process includes the steps of (c) reacting a 4-(perfluoroalkyl)alkoxybenzene with acetic anhydride or an acyl halide in the presence of a Lewis acid, thereby obtaining a 2-alkoxy-5-(perfluoroalkyl)acetophenone; and (d) dealkylating the 2-alkoxy-5-(perfluoroalkyl) acetophenone by a dealkylating agent.

    摘要: Disclosed is a process for producing α-substituted norbornanyl acrylates efficiently on an industrial scale while suppressing the formation of by-products derived from intramolecular cyclization, excessive addition to acrylic acid etc. The α-substituted norbornanyl acrylates are useful as norbornene resist monomers. In the disclosed process, an α-substituted acrylic acid is directly reacted with a substituted norbornene in the presence of at least one acid catalyst selected from methanesulfonic acid and camphorsulfonic acid. It is possible in this reaction to suppress the formation of the by-products derived from intramolecular cyclication, excessive addition of the acid to the reaction product etc.

    摘要: A benzyl vinyl ether represented by the following formula is hydrolyzed in the presence of a catalyst selected among Arrhenius acids and Lewis acids to obtain 3,3,3-trifluoropropionaldehyde. Subsequently, the 3,3,3-trifluoropropionaldehyde is oxidized with an oxidizing agent. Thus, 3,3,3-trifluoropropionic acid can be more advantageously produced than in conventional techniques from an inexpensive starting material.
