Highly active iron catalysts for olefin hydrogenation enable para -hydrogen induced hyperpolarisation of 1 H and 19 F NMR resonances at 1.4 Tesla

Year: 2025

Type: article

Abstract: Parahydrogen induced polarisation (PHIP) is an excellent tool for extracting mechanistic information in catalysis since it circumvents the intrinsic low sensitivity of nuclear magnetic resonance (NMR) spectroscopy. We report a class of iron complexes, which are highly active in olefin hydrogenation catalysis and act as PHIP catalysts at 1.4 Tesla. Moreover, hyperpolarisation transfer to 19F is observed.
