Dalton communications. Rapid characterisation of rhodium dihydrides by nuclear magnetic resonance spectroscopy using indirect two-dimensional methods and para-hydrogen
Abstract
When [RhH2(PMe3)3Cl], incorporating chemically inequivalent hydrides, and [RhH2(PMe3)4]Cl, containing magnetically inequivalent hydrides, were generated using para-enriched hydrogen, their 1H–103Rh and 1H–31P two-dimensional NMR spectra were quickly obtained from < 1 mg of complex with and without the aid of pulsed field gradients.
