“…We focused our studies on six model compounds: vinyl acetate, coumarin, (−)-isopulegol, cinnamaldehyde, citronellal, and linalool, with some consideration of the fragrances eugenol, estragole, and benzaldehyde. The hydrogenation reactions of vinyl acetate, coumarin, − cinnamaldehyde, − citronellal, , and (−)-isopulegol , have been previously realized in continuous flow, but, to the best of our knowledge, never over additively manufactured catalysts or catalyst supports. We tested the hydrogenation of these six molecules over five sets of CSMs coated with one of four different metal catalyst species, namely palladium, platinum, ruthenium, and nickel.…”
