Table 2. Substrate Scope for the Catalytic Hydrogenative Depolymerization of Polyamides^a.

^aCatalytic conditions: polyamide (1 mmol relative to the molecular weight of the monomer), complex 1 (0.02 mmol), KO^tBu (0.08 mmol), DMSO (2.5 mL), H₂ (70 bar), temperature 150 °C, and reaction time 48 h.

^bTwo sequential hydrogenation steps both in DMSO (vide supra).

^cTwo sequential hydrogenation steps first in DMSO and second in 1,4-dioxane (vide supra).

^d2 (0.05 mmol) and KO^tBu (0.2 mmol), 72 h, remaining conditions as above in footnote a.

^eMolecular weight could not be determined.
