Pd−In/Al 2 O 3 single‐site catalyst was able to show high selectivity in the gas phase semihydrogenation of propyne. When parahydrogen was used 3400‐fold NMR signal enhancement for reaction product propene was observed, demonstrating the large contribution of pairwise hydrogen addition route. Significant signal enhancement as well as the high catalytic activity of the Pd−In catalyst allowed to acquire 1 H MR images of hyperpolarized propene. This observation is unique and can be easily transferred to the development of a useful MRI technique for an in situ investigation of selective semihydrogenation in catalytic reactors.
