Palladium-catalyzed Suzuki-Miyaura coupling reactions of ethyl α-bromo-α-fluoroacetate with various structurally diverse arylboronicacids using a phosphine ligand proceeded smoothly to afford α-aryl-α-fluoroacetates in moderate to good yields. This method provides a practical and efficient route to diverse α-monofluorinated α-arylcarbonyl compounds. cross coupling - fluorinated compounds - boronic

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

A palladium-catalyzed monofluoroalkylation of aryliodides and arylbromides was developed using nucleophilic ethyl 2-fluoro-2-(trimethylsilyl)acetate as a monofluoroalkyl source. The transformation proceeded with excellent substrate scope to afford a range of monofluoroalkylated products in good yields under mild conditions, and it proved feasible in a gram-scale reaction. This protocol was successfully
