MOF负载二亚胺镍催化高活性丙烯二聚反应
MOF-Supported Diimine-Ni Catalyzed Highly Active Propylene Dimerization
摘要
Abstract
A heterogeneous diimine-Ni catalyst(diimine-Ni@PCN-701)is synthesized through sequential ligand insertion into PCN-700,a robust Zr-based metal-organic framework(MOF),followed by chelation of Ni centers.This site-specific assembly affords a robust active center for propylene dimerization with superior activity,which arises from the electron-withdrawing effect of Zr6 O4(OH)4 clusters on the Ni active sites.Propylene is selectively converted into a series of dimers with 4-methyl-2-pentene(4M2P)as the main product,which may be due to the MOF structure promoting this reaction through both electronic effects and steric hindrance.This work highlights a general strategy for developing heterogeneous olefin oligomerization catalysts with high activity and shape selectivity through the precise construction of active sites.关键词
