- Quantification of relevant Brønsted acid sites on Cl-doped alumina catalysts for the isomerization of olefins： 该研究探索了Cl掺杂氧化铝对3,3-二甲基-1-丁烯异构化反应的催化活性，说明了异构化效率与催化剂特定Brønsted酸位点的线性关系。(Q Rivet, R Beucher, F Morfin, T Nardin, D Farrusseng, Journal of Catalysis, 2023)。
General description
3,3-二甲基-1-丁烯通过氯促进的 Ag（111）氧原子选择性地氧化成相应的环氧化物。3,3-二甲基-1-丁烯使用链行走 Pd-二亚胺催化剂与乙烯共聚。3,3-二甲基-1-丁烯（叔丁基乙烯）的阳离子聚合是在 -31 至-130°C 的温度范围内，使用 AlCl3 催化剂在氯乙烷溶剂中进行的。
