A combinatorial nickel-catalyzed monofluoroalkylation of aryl bromides with the industrial raw regent ethyl chlorofluoroacetate has been developed. The two key factors to successful conversion are the combination of nickel with readily available nitrogen and phosphine ligands and the using of a mixture of different solvents. Mechanistic investigations indicated a new zinc regent might generated in situ and be involved in the reaction process.

Herein, we report the radiosynthesis of 18F-difluoromethylarenes via the assembly of three components, a boron reagent, ethyl bromofluoroacetate, and cyclotron-produced non-carrier added [18F]fluoride. The two key steps are a copper-catalysed cross-coupling reaction, and a Mn-mediated 18F-fluorodecarboxylation.

A palladium-catalyzed Negishi cross-coupling reaction of ethyl bromodifluoroacetate with aryl bromides or aryl triflates to construct C(sp2)-CF2 bonds is described. The reaction was conducted under mild reaction conditions, and no preparation of organozinc reagents is required. This is the first report encompassing the conversion of aryl triflates into products containing C-CF2 bonds. In addition, the construction of C(sp2)-CHF bonds was achieved under mild conditions via a cross-coupling of aryl iodides with ethyl bromofluoroacetate.
Palladium-catalyzed cross-coupling of ethyl α-bromo-α- fluoroacetate with arylboronic acids: Facile synthesis of α-aryl-α- fluoroacetate

Palladium-catalyzed Suzuki-Miyaura coupling reactions of ethyl α-bromo-α-fluoroacetate with various structurally diverse arylboronic acids using a phosphine ligand proceeded smoothly to afford α-aryl-α-fluoroacetate in moderate to good yields. This method provides a practical and efficient route to diverse α-monofluorinated α-arylcarbonyl compounds. Georg Thieme Verlag Stuttgart New York.
