Schematic view of the hydrogenation reaction of FUM to SUC. pH2 is added to FUM via a Rh‐catalyst at 90 °C and 20 bar. After hydrogenation, spin order is transferred from pH2 into 13C‐magnetization by means of pulse sequences and the J‐coupling network. Note that the protons do not reveal a chemical shift difference.
