(a) Hydrogen uptake curves in the hydrogenation of (i) Diphenylacetylene (DPA) over Pd-intB/C catalyst (black); (ii) DPA over Lindlar’s catalyst (red); (iii) Phenylacetylene (PA) over Pd-intB/C catalyst (green); (iv) PA over Lindlar’s catalyst (blue). Conditions: 2.50 mmol alkyne, 2.50 μmol catalyst, EtOH, 3 bar H2, 30 °C, 1,200 r.p.m. H2 uptake value of ~62 ml for 1 mole equiv. to alkyne. (b) Structure of substrate molecule (top: DPA, bottom: PA).
