complexes are easily synthesized by palladium-catalyzed C−P cross-coupling of vinyl triflates with secondary phosphine−boranes. This method allows the synthesis of phosphine derivatives not always easily accessible by other approaches. The vinylphosphine derivatives are purified by chromatography on silica gel. The versatility of the method is proved by using various triflates and diaryl-, dialkyl- and al
