Abstract

A new method for selective and efficient cleavage of arylglycerol-β-aryl (β-O-4) ether linkages in lignins is described and applied to several lignin β-ether models. The term “DFRC” was coined for derivatization followed by reductive cleavage. Derivatization, accompanied by cell wall solubilization, is accomplished with acetyl bromide (AcBr); reductive cleavage of resulting β-bromo ethers utilizes zinc in acetic acid. Degradation ...
