P–C Cross‐Coupling Onto Enamides: Versatile Synthesis of α‐Enamido Phosphane Derivatives

We report herein the Pd‐catalyzed P–C cross‐coupling reaction between enol phosphates and secondary phosphane–borane complexes or phosphane oxides. The reaction was performed under mild conditions, owing to Pd activation of the P–H bonds of the phosphane–boranes (or phosphane oxides) and to the powerful enol phosphate coupling reagents. New useful chiral and achiral α‐β‐alkenylphosphane derivatives bearing an amido group in the α‐position to the P center were obtained in yields up to 70 %.
