conversions and reasonable yields. Thus, regardless of the relatively low electron density, =CH–CH= conjugated units of molecules, including compound 2 as a sustainable, non-foodstuff source, can be utilized as building blocks for the synthesis of various value-added chemicals via olefinmetathesis. DFT-studies and the product spectrum of the self-metathesis of 1,6-diphenyl-1,3,5-hexatriene suggest
1-Alkylbenzenes as a precursor of surfactants, can be produced from ethylene, styrene, and hydrogen. These intermediates, lacking tertiary carbons, are environmentally more benign than commercial ones that bear the aromatic ring linked to an internal carbon of the aliphatic chain. The one-pot synthesis of highly linear 1-alkylbenzenes (LABs) through the homogeneous catalysis of olefin poly-insertion
1-烷基苯作为表面活性剂的前体,可以由乙烯、苯乙烯和氢气生产。这些没有叔碳的中间体比带有与脂肪链内部碳相连的芳环的商业中间体对环境更友好。通过烯烃多插入的均相催化从廉价且大量可用的试剂中一锅法合成高度线性的 1-烷基苯 (LAB) 可以以高周转率和选择性进行。一个专门设计的反应器可以对三种成分的进料以及温度进行精细控制,在这一成就中起着关键作用。在同时去除作为副产物的聚乙烯的情况下,可以获得每小时 194 g LABs/mmol 催化剂的转化率。
