The same transformation was studied using the Pd/C catalyzed strategy, as a representation of the conventional method. The flow diagram of the method is represented in Scheme S8. It starts with the addition of Pd/C in a round-bottom flask and dispersed in ethanol (Scheme S8, flow 1). The system was sealed and purged 3 times with nitrogen and 3 times with hydrogen (Scheme S8, flows 2-3). A hydrogen balloon (1 L) was then attached to the set up. The substrate, dissolved in ethanol, was added for over 210 minutes. 30 minutes later, the flask was purged with nitrogen (Scheme S8, flows 4-8). The suspension was then filtered over a phase separator (Scheme S8, flows 9-12). The product could be isolated from the mother liquor via fractional distillation (Scheme S8, flows 12-14).
