22. Hydroxymethyl polystyrene (100-200 mesh, 1% divinylbenzene; substitution: 1.13 mmol/g) was purchased from Novabiochem.
23. The resulting polymer (3.37 wt % Ru) was characterized by IR. See the Supporting Information.
24. When the DKR was completed, the reaction mixture was extracted with hexane five times. The residue was dried under vacuum and stored for reuse.
