Stereospecific Cross-Coupling of Secondary Alkyl β-Trifluoroboratoamides

The stereospecific cross-coupling of enantioenriched nonbenzylic secondary alkyl boron compounds has been achieved. The high selectivity toward product formation over an undesired beta-H elimination pathway is achieved via an intramolecular coordination of an ancillary carbonyl to the metal center in the diorganopalladium intermediate.
