Evidence for Direct Transmetalation of AuIII-F with Boronic Acids.
The underlying reactivity of AuIII-F species with aryl boronic acids has been studied in detail taking advantage of four novel, stable difluoro-[(C^N)AuF2], arylmonofluoro-[(C^N)AuArF], and alkylmonofluoro-[(C^N)AuAlkF] gold(III) complexes, prepared and isolated in monomeric form. We provide the first experimental evidence for a direct AuIII-F/B transmetalation preceding the Csp2-Csp2or Csp3-Csp2bond formation.
