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

Abstract

para-Hydrogen 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 that are highly active in olefin hydrogenation catalysis and act as PHIP catalysts at 1.4 Tesla. Moreover, hyperpolarisation transfer to 19F is observed.
