Fig. 4. Amine substrates polarised by SABRE using precatalyst 1 in dichloromethane-d2 solution. Per proton signal gains are given for the indicated 1H sites (* average across two sites due to peak overlap) observed at 9.4 T. Corresponding 1H NMR spectra for thermally polarised and SABRE polarised experiments are given in the ESI.† .
