Fig. 4. Partial a) 13C and b) 1H hyperpolarised NMR spectra resulting from shaking a sample of [IrCl(COD)(IMes)], 5 equivalents of sodium pyruvate-1,2-[13C2], and 10 equivalents of DMSO with varying amounts of NaCl in 0.6 mL methanol-d4 with 3 bar p-H2 for 10 seconds, a) in a mu metal shield 35 minutes following the initial H2 addition step and b) at 65 G, 10 minutes following the initial H2 addition step.
