摘要： An object of the present invention is to provide a process for producing α-fluoroacrylic acid esters at a high starting material conversion and a high yield. The present invention provides, as a means to achieve the object, a process for producing a compound represented by formula (1): wherein R1 and R2 are the same or different and each represent alkyl, fluoroalkyl, aryl optionally substituted with at least one substituent, halogen, or hydrogen; and R3 represents alkyl, fluoroalkyl, or aryl optionally substituted with at least one substituent, the process comprising step A of reacting a compound represented by formula (2): wherein the symbols are as defined above, with carbon monoxide and an alcohol represented by formula (3): R3—OH (3) wherein the symbol is as defined above, in the presence of a transition metal complex catalyst containing at least one bidentate phosphine ligand and a base to thereby obtain the compound represented by formula (1).

摘要： An object of the present invention is to provide a novel substance that has a high reactivity as a fluorinating agent, is effectively used in various fluorination reactions, and is safely handled even in air. As the solution for achieving this object, the present invention provides a complex obtained by reacting bromine trifluoride with at least one metal halide selected from the group consisting of halogenated metals and halogenated hydrogen metals in a nonpolar solvent. This complex serves as a fluorinating agent that provides excellent fluorination performance and that is stable in air.

摘要： A film forming method is a method of forming a film on a substrate top face including a first region in which a metal or a semiconductor is exposed and a second region in which an insulator is exposed. The method includes a SAM forming process of forming a self-assembled monolayer film of a perfluoropolyether group-containing compound on the first region and a film growth process of forming a predetermined film on the second region after execution of SAM forming process.
