efficient transition metal triflate catalyzed approach to convert biomass-based compounds, such as monoterpene alcohols, sugar alcohols, octyl acetate and tea tree oil, to their corresponding olefins in high yields. The reaction proceeds through C–O bond cleavage under solvent-free conditions, where the catalytic activity is determined by the oxophilicity and the Lewis acidity of the metal catalyst
在此,我们报告了一种有效的过渡金属三氟甲磺酸盐催化方法,以高产率将基于生物质的化合物(如单萜醇、糖醇、乙酸辛酯和茶树油)转化为相应的烯烃。该反应在无溶剂条件下通过 C-O 键断裂进行,其中催化活性由金属催化剂的亲氧性和路易斯酸性决定。此外,我们展示了含氧官能团如何影响烯烃的形成。此外,所用金属三氟甲磺酸盐催化剂 Fe(OTf) 3和 Hf(OTf) 4的稳健性突出表现在它们能够以高分离产率将超过 2400 倍过量的 2-辛醇转化为辛烯。
