catalyze the metal‐free hydrosilylative reduction of monosaccharides and polysaccharides to give hydrocarbons with reduced oxygen content. The choice of the silane reductant influences the degree of deoxygenation, with diethylsilane effecting the complete reduction to produce hexanes while tertiary silanes give partially deoxygenated tetraol and triol products.
易于获得的纤维素生物质向有价值的原料和燃料的转化是一个吸引人的目标,但具有挑战性的转化需要裂解多个未活化的CO键。在此,路易斯酸三五氟苯基硼烷(B(C 6 F 5)3)被证明可催化单糖和多糖的无金属氢化硅烷化还原,从而制得氧含量降低的烃。硅烷还原剂的选择会影响脱氧程度,二乙基硅烷会完全还原生成己烷,而叔硅烷会产生部分脱氧的四醇和三醇产物。
