The first metal-free reduction of lignin model compounds is described. Using inexpensive Et3SiH, PMHS and TMDS hydrosilanes as reductants, α-O-4 and β-O-4 linkages are reduced to primary alcohols and phenols under mild conditions using B(C6F5)3 as an efficient catalyst.
首次描述了木质素模型化合物的无金属还原。使用廉价的 Et3SiH、PMHS 和 TMDS 硅氢烷作为还原剂,在温和条件下,使用 B(C6F5)3 作为高效催化剂,将 α-O-4 和 β-O-4 键还原为伯醇和酚。
