Values were obtained from a 1.00 g scale reaction (Scheme S9 and Table ). The recyclability properties of Pd/C were studied using 1a as substrate, as the slow addition required for 1b hampered the evaluation at low conversions. Several techniques were explored to recover the Pd/C after the reaction, being the filtration via phase separator the one that gave better performance (Scheme S10). The method showed a good but fluctuating performance for at least 10 runs, obtaining the desired hydrogenated product 2a in 29±6.8% yields after 20 min (Scheme S11). The mass loss of palladium was not evaluated due to its pyrophoric nature. We assumed a similar performance regarding its recyclability, and a value of 52 cycles will be used. Moreover, 4% of ethanol was lost during the distillation step. Gasses were not recovered and released to the atmosphere. Its applicability was also tested for a variety of enones at shorter reaction times, but showed lower chemoselectivity, as ketone reduction was also accessed (Scheme S12). Formation of alcohol 3a as over hydrogenation by-product takes place in parallel to the desired hydrogenation from 1a to 2a (Scheme S13).
