Competition between sp³-C-N vs sp³-C-F reductive elimination from Pd(IV) 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.
