本文报道了碱催化木质素β-O-4模型化合物在碳酸二甲酯中的转化和裂解。该反应体系由容易获得的碱和廉价的碳酸二甲酯作为溶剂和试剂组成，以良好至非常好的产率提供甲氧基苯或2-芳氧基乙烯基苯衍生物。证明了该系统对有机溶剂木质素样品中键断裂的适用性。
A base-catalysed transformation and cleavage of lignin beta-O-4 model compounds in dimethyl carbonate is reported. The reaction system consists of readily available bases and inexpensive dimethyl carbonate as a solvent and reagent, affording methoxy benzene or 2-aryloxyvinyl benzene derivatives in good to very good yields. The applicability of the system for the bond cleavage in an organosolv lignin sample was demonstrated.
