Fig. 2: Catalytic disconnection on model compounds and reactivity of TMM ligand.

a Comparison between epoxy model and lignin model compounds. Yields determined using 1H NMR spectroscopy using 1,3,5-trimethoxybenzene as internal standard. b TMM versus phosphine as active ligand. c Complexation of TMM ligand by IPrAu cations forming a diaurated 2-methyleneallyl ruthenium complex (proposed structure). Molecular structure of triphos-Ru-methylallyl-CO in the crystal (CCDC 2303540). d Proposed mechanism for deuterium incorporation. Ratio of incorporation determined using 1H and 2H NMR spectroscopy. TMM trimethylenemethane, triphos 1,1,1-tris(diphenyl-phosphinomethyl)ethane, Me-BPA O-methyl bisphenol A.
