The cleavage of representative lignin systems has been achieved in a metal‐free two‐step sequence first employing nitrogen monoxide for oxidation followed by hydrazine for reductive C−O bond scission. In combining nitrogen monoxide and lignin, the newly developed valorization strategy shows the particular feature of starting from two waste materials, and it further exploits the attractive conditions of a Wolff‐Kishner reduction for C−O bond cleavage for the first time.

一氧化氮和肼对木质素系统的顺序裂解

代表性木质素系统的裂解已在无金属的两步骤序列中完成，首先使用一氧化氮进行氧化，然后使用肼进行还原性C-O键断裂。通过将一氧化氮和木质素结合在一起，新开发的增值策略显示了从两种废料开始的特殊特征，并且它进一步利用了Wolff-Kishner还原的引人注目的条件首次将C-O键裂解。
