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.
