Die Plätze getauscht : In Gegenwart eines Platin‐Phosphan‐Katalysators findet ein intramolekularer B(pin)/H‐Austausch statt (siehe Schema; B(pin)=4,4,5,5‐Tetramethyl‐1,3,2‐dioxaborolan‐2‐yl). Dabei bilden sich stereoselektiv cis ‐β‐Methyl‐substituierte Alkenylboronate, die nützliche Synthesebausteine sind.
