Journal ArticleDOI
Application of parahydrogen induced polarization techniques in NMR spectroscopy and imaging.
Simon B. Duckett,Ryan E. Mewis +1 more
TL;DR: This Account describes the use of parahydrogen to hyperpolarize a suitable substrate and describes the characterization of organometallic reaction intermediates including those involved in catalytic reactions, either with or without hydride ligands.

Hyperpolarization of 13C through order transfer from parahydrogen: A new contrast agent for MRI
TL;DR: The order within proton pairs in organic molecules, resulting from hydrogenation with parahydrogen, can be transferred in great part to nearby carbon 13 spins through adequate field manipulations, and the molecules with hyperpolarized 13C thus obtained can be used as new contrast agents of high efficiency in MRI.
Journal ArticleDOI
Transfer of para-hydrogen spin order into polarization by diabatic field cycling
TL;DR: Johannesson et al. as mentioned in this paper used diabatic field cycling to obtain a substantial net polarization of a hetero nucleus using a diabolical field cycling scheme, which was experimentally demonstrated for hydroxyethyl propionate.
Journal ArticleDOI
Parahydrogen-based NMR methods as a mechanistic probe in inorganic chemistry
TL;DR: In this article, an overview of how chemical reactions can be studied using parahydrogen-assisted NMR spectroscopy, where detected signals can have strengths that exceed those normally available by factors that approach 31,000.
Journal ArticleDOI
Cobalt-Catalyzed and Lewis Acid-Assisted Nitrile Hydrogenation to Primary Amines: A Combined Effort
TL;DR: Mechanistic insights gleaned from para-hydrogen induced polarization (PHIP) transfer NMR studies revealed that the pairwise hydrogenation of nitriles proceeded through a Co(I/III) redox process.
