When used in catalytic hydrogenations, parahydrogen can enhance NMR signals of reaction products and intermediates by several orders of magnitude owing to the phenomenon of parahydrogen-induced polarization (PHIP). This possibility has been explored previously in the context of activation of molecular hydrogen by transition metal complexes and clusters in solution. After a brief introduction to parahydrogen and PHIP basics, the applications of PHIP as a mechanistic tool in homogeneous catalysis are briefly reviewed to demonstrate the possibilities and the information that PHIP-based NMR spectroscopy studies of such processes can provide. Then, the emerging applications of PHIP-enhanced NMR in heterogeneous catalysis are presented, both for metal complexes immobilized on solid supports and for supported metal catalysts, and the implications of these results for the mechanisms of heterogeneous hydrogenation processes are discussed.
