Competition between sp3-C-N vs sp3-C-F Reductive Elimination from PdIV Complexes

This communication describes the design of a model system that allows direct investigation of competing sp(3)-C-N and sp(3)-C-F bond-forming reductive elimination from a Pd-IV fluoro sulfonamide complex. The reductive elimination selectivity varies dramatically as a function of reaction additives. A mechanism is proposed that provides a rationale for these effects.
