Nuclear magnetic resonance (NMR) is an extremely powerful method for in situ monitoring of chemical reactions and mass transport processes.[1] However, the low intrinsic sensitivity of NMR resulting from low thermal nuclear spin polarization limits the use of the method. Several hyperpolarization techniques have been developed for boosting the sensitivity.[2] Among them, parahydrogen-induced polarization (PHIP) has a direct relation to chemistry, as the hyperpolarization is naturally produced in the course of a chemical reaction proceeding through the addition of parahydrogen.[3] Originally, PHIP was discovered in a homogeneous catalytic hydrogenation, and since then many homogeneous catalytic systems have been shown to produce PHIP.[3a, c] Within the past five years, several catalysts have been found to enable the production of PHIP in heterogeneously catalyzed hydrogenations.[4, 5] Catalyst …
