A new in situ NMR method for the structural characterization of hydrogenation intermediates based on the PHIP effect (PHIP= p ara h ydrogen‐ i nduced p olarization): by means of a nuclear Overhauser effect (NOE) the intermediate bonding of hydrogenated [D 8 ]styrene to cationic Rh I –diphosphane catalyst complexes could be detected (see picture).
