(a) Hydrogen uptake curves in the hydrogenation of 3-hexyn-1-ol for: (i) non-modified 3% Pd/C (black); (ii) Pd-intB/C (blue); (iii) Lindlar’s 5% PdPb/CaCO3 (red). Conditions: 30 mmol 1,4-dioxane and 3-hexyn-1-ol, 2.80 μmol catalyst in EtOH, 3 bar H2, 30 °C, 400 r.p.m., Parr autoclave. H2 uptake value of ~650 ml for 1 mol equiv. to alkyne. (b) GC results for the stereoselective hydrogenation of 3-hexyn-1-ol. Stop: sample collected before the change in hydrogen uptake. End: sample collected at the end of hydrogen uptake. THEL, trans-hexen1-ol; CHEL, cis-hexen-1-ol; HAL, 1-hexanol. Yellow dot represents percent of conversion.
