Manipulation of lignin condensation pathways to produce different bisphenols from biomass.

ABSTRACT: Valorization of lignin is essential for establishing a profitable biorefining industry, yet its efficiency is critically constrained by lignin condensation. Understanding lignin condensation mechanisms and developing effective strategies to inhibit condensation have emerged as a global research imperative. Despite several successful practices in stabilizing the α carbon position of lignin under mild temperatures, a mechanistic understanding of lignin condensation under high temperatures and the corresponding strategy for preventing such condensation remain lacking. Herein, using monophenol as a probe molecule to capture reactive lignin fragments produced under high-temperature treatments, we unveil a novel condensation pathway involving the C_γ-position, which arises from the nuc
