Table 2. Rate constants for H₂ production (k_(obs)H2) and hydride interchange (k_(obs)Hi) of 2A determined by EXSY at 273 K as a function of H₂ pressure when amine concentration was fixed at 15 eq. relative to iridium precatalyst.

H2 pressure	k (obs)H2/s–1	k (obs)Hi/s–1
1 bar	0.60 ± 0.01	1.05 ± 0.01
2 bar	0.95 ± 0.01	0.92 ± 0.01
3 bar	1.13 ± 0.01	0.88 ± 0.01
