摘要

本研究研究了pd催化木质素的串联还原解聚和随后的Co（salen）催化氧化裂解得到苯醌和苯甲醛。还原性解聚会导致木质素大分子的酚OH含量大量增加，然后被Co（salen）催化剂选择性地裂解，生成苯醌和苯甲醛。与木质素样品相比，不进行还原性解聚首先，苯醌的产量大大增加。

Reductive-Oxidative Tandem Catalysis for Lignin Depolymerization to Benzoquinones and Benzaldehydes.

This study investigates a tandem Pd-catalyzed reductive depolymerization of lignin and subsequent Co(salen)-catalyzed oxidative cleavage to obtain benzoquinones and benzaldehydes. The reductive depolymerization will result in lignin macromolecules with heavily increased phenolic OH content, which are then selectively cleaved by the Co(salen) catalyst to yield benzoquinones and benzaldehydes. Compared to lignin samples that do not undergo reductive depolymerization first, benzoquinone yields are substantially increased.
