Paragraph 0071-0073, (2018/10/03)
PROBLEM TO BE SOLVED: To provide (trifluorovinyl)benzenes and a method for producing the same.SOLUTION: The method for producing (trifluorovinyl)benzenes expressed by general formula (3) comprises carrying out a reaction of a phenyl boron compound with trifluorohaloethylenes in the coexistence of 1 to 100 equivalents of water with respect to the phenyl boron compound (1), a palladium complex coordinated with a bidentate phosphine ligand, and an alkali metal salt. In formula (3), Rrepresents a hydrogen atom or a formyl group; Rand Reach independently represents a hydrogen atom, 1-4C alkyl group, 2-4C alkenyl group, 2-5C acyl group, (1-4C alkoxy)carbonyl group, 1-4C alkoxy group, tri(1-4C alkyl)silyl group, 2-5C acylamino group, cyano group, phenyl group, chlorine atom, fluorine atom or nitro group; and adjoining Rand Rmay form a ring together with a carbon atom bonded thereto.

A new strategy for C-C bond formation with organoboronates through C-F activation of fluorinated alkenes and arenes was developed. In this Pd-catalyzed Suzuki-Miyaura-type cross-coupling reaction, neither a base for enhancing the reactivity of the organoboron reagents nor a Lewis acid for promoting C-F bond activation was required. A fluoropalladium intermediate played an essential role in this reaction. In addition, a Ni(NHC) catalyst was efficient for C-C coupling through C-F bond activation of fluoroarenes. Pd0/PR 3 complexes promote C-C bond formation with organoboronates through C-F bond activation of fluorinated alkenes. Mechanistic studies show that a PdII fluoride intermediate plays an essential role in this base-free cross-coupling reaction. Moreover, a Ni(NHC) catalyst is efficient for C-C coupling through C-F bond cleavage of fluoroarenes. Copyright
