摘要：
The present invention provides methods and catalyst compositions for the catalytic reduction of carbon-oxygen bonds of organic substrates and the catalytic disproportionation of carbon-oxygen or carbon-carbon bonds of organic substrates. These methods and catalyst compositions may be used to depolymerize lignin. The disproportionation of carbon-oxygen or carbon-carbon bonds of organic substrates or lignin is carried out by cleaving a carbon-oxygen bond or a carbon-carbon bond in a catalytic disproportionation reaction. The catalysts may be formed from a metal precursor such as ruthenium or vanadium and a bidentate ligand The catalytic reduction of carbon-oxygen bonds of organic substrates such as lignin is carried out by cleaving a carbon-oxygen bond in the presence of a hydrogen atom source. Lignin fragments produced following depolymerization by such methods may be further processed into fuels.
摘要（中）：
本发明提供用于催化还原有机底物的碳 - 氧键的方法和催化剂组合物以及有机底物的碳 - 氧或碳 - 碳键的催化歧化。 这些方法和催化剂组合物可用于解聚木质素。 有机底物或木质素的碳 - 氧或碳 - 碳键的歧化是通过在催化歧化反应中裂解碳 - 氧键或碳 - 碳键进行的。 催化剂可以由诸如钌或钒的金属前体和双齿配体形成。有机基质如木质素的碳 - 氧键的催化还原通过在氢原子源存在下裂解碳 - 氧键来进行 。 通过这种方法解聚后产生的木质素碎片可进一步加工成燃料。
