Iridium trihydride and tetrahydride complexes and their role in catalytic polarisation transfer from parahydrogen to pyruvate This work details how the unusual iridium tetrahydride [Ir(H)4(IMes)(sulfoxide)]Na can be formed in a solvent dependent reaction of [IrCl(COD)(IMes)] with sulfoxide (dimethyl or methylphenyl), base, and H2. In the case of dimethyl sulfoxide, the four hydride ligands are equivalent, and the IMes and sulfoxide ligands mutually trans.

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.
