Abstract A novel carbon-increasing catalytic route via one-pot cascade acylation–alkylation of biomass-derived 2-methylfuran and acetic anhydride over Sn4+-exchanged K-10 montmorillonite (Sn4+-K-10) was demonstrated to be highly efficient for the production of C17 oxygenate 1,1,1-tris(5-methyl-2-furyl)ethane with a high yield of 87% and 90% selectivity at 60 °C in 8 h under solvent-free conditions. Characterization techniques manifested Sn4+-K-10 to have layered and mesoporous (5.7 nm) texture structure, Lewis–Bronsted acid paired sites and uniformly dispersed Sn species, which greatly contributed to the predominant reactivity and recyclability of Sn4+-K-10. Systematic studies based on GC–MS and NMR were also conducted to elucidate the catalytic mechanism.

摘要 生物质衍生的 2-甲基呋喃和乙酸酐在 Sn4+ 交换的 K-10 蒙脱石 (Sn4+-K-10) 上通过一锅级联酰化-烷基化的新型增碳催化路线被证明是高效的生产C17 氧化 1,1,1-三（5-甲基-2-呋喃基）乙烷，在无溶剂条件下，在 60°C 下 8 小时内以 87% 的高产率和 90% 的选择性。表征技术表明 Sn4+-K-10 具有层状介孔 (5.7 nm) 织构结构、路易斯-布朗斯台德酸配对位点和均匀分散的 Sn 物种，这极大地促进了 Sn4+-K-10 的主要反应性和可回收性。还进行了基于 GC-MS 和 NMR 的系统研究，以阐明催化机制。
