Figure 2

Hydride region of a series of 1H NMR spectra of a reaction mixture of 1, 2, and pyr-d5 in CD3OD under ∼4 bar of p-H2 pressure indicating the formation of 3 (blue ★). The purple ● correspond to [Ir(H)2(d22-IMes)(pyr-d5)3]Cl and its H/D analogue. The product indicated by the green ◆ is unidentified, and it is not detected at low temperature: (a) 1H NMR spectrum at 298 K; (b) 1H NMR spectrum at 273 K; and (c) 1H{15N} NMR spectrum at 273 K.
