Kusumoto, Shuhei; Kishino, Masamichi; Nozaki, Kyoko published an article in 2020, the title of the article was Cleavage of C-C and C-O Bonds in β-O-4 Linkage of Lignin Model Compound by Cyclopentadienone Group 8 and 9 Metal Complexes.COA of Formula: C8H10O2 And the article contains the following content:
Degradation of 1-(3,4-dimethoxyphenyl)-2-(2-methoxyphenoxy)propane-1,3-diol (1), a model compound for lignin β-O-4 linkage was examined with iron, ruthenium, rhodium and iridium complexes bearing cyclopentadienone ligand. Cyclopentadienone iron complex gave only a small amount of degraded product with reduced mol. weight Cyclopentadienone ruthenium complex, so called Shvo’s catalyst, afforded 3,4-dimethoxybenzaldehyde (a3) in 14.3% yield after Cα-Cβ bond cleavage. On the other hand, cyclopentadienone group-9 metal complexes catalyzed Cβ-O bond cleavage to afford guaiacol (b1) as a main product in up to 74.9% yield. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).COA of Formula: C8H10O2
The Article related to lignin metal ligand cooperation retro aldol reaction, Cellulose, Lignin, Paper, and Other Wood Products: Lignin and other aspects.COA of Formula: C8H10O2
