Figure 5.

Initial reaction rate of the hydrogenation of 1 over (a) Ir–Mo- and Ir–V-based catalysts, (b) Ir/MoO₃, and (c) Ir₄Mo₄/Al₂O₃ with different Ir loadings. Reaction conditions were identical to those cited in the caption of Figure 4 except for the catalyst amount (2–100 mg, Ir: 0.52 mol %). The original data are summarized in Table S3.
