Analysis of chemical exchange in iridium N-heterocyclic carbene complexes using heteronuclear parahydrogen-enhanced NMR - Communications Chemistry

Dec 2, 2024 | nature.com | Xin Gui |Oleg Salnikov |Arne Brahms |Eduard Y Chekmenev |Rainer Herges |Simon B Duckett | +2 more

AbstractThe signal amplification by reversible exchange process (SABRE) enhances NMR signals by unlocking hidden polarization in parahydrogen through interactions with to-be-hyperpolarized substrate molecules when both are transiently bound to an Ir-based organometallic catalyst. Recent efforts focus on optimizing polarization transfer from parahydrogen-derived hydride ligands to the substrate in SABRE.
