Development of highly active heterogeneous catalysts is an effective strategy for modern organic synthesis chemistry. In this work, acidic mesoporous zeolite ZSM-5 (HZSM-5-M), acidic-free mesoporous zeolite TS-1 (TS-1-M), and basic ETS-10 zeolite supported metal Cu catalysts were prepared to investigate their catalytic performances in the hydroxysulfurization of styrenes with diaryl disulfides. The effect of pore size and acidities of the supports, as well as the Cu species electronic properties of the catalysts on reaction activity were investigated. The results show that Cu⁺ and Cu binded on HZSM-5-M show the highest activity and product selectivity for the desired -hydroxysulfides compounds.
开发高活性多相催化剂是现代有机合成化学的有效策略。在本工作中，制备了酸性介孔沸石ZSM-5（HZSM-5-M）、无酸性介孔沸石TS-1（TS-1-M）和负载金属Cu的碱性ETS-10沸石催化剂，以研究它们在苯乙烯与二芳基二硫化物的羟基硫化反应中的催化性能。研究了载体的孔径和酸度以及催化剂的Cu物种电子性质对反应活性的影响。结果表明，负载在HZSM-5-M上的Cu⁺和Cu对所需的羟基硫化物化合物表现出最高的活性和产物选择性。
