Multiwalled carbon nanotubes were highly functionalized with catechol moieties by means of a simple procedure involving the in-situ generation of the diazonium salt arising from the reaction between 4-aminocatechol and isoamyl nitrite. The resulting material was used to immobilize Pd nanoparticles obtaining an active and recyclable catalyst for the Heck reaction between methyl acrylate/styrene and aryl iodides.

儿茶酚功能化碳纳米管作为 Pd 纳米颗粒的载体：用于 Heck 反应的可回收系统

多壁碳纳米管通过简单的程序用儿茶酚部分高度官能化，该程序包括原位生成由 4-氨基儿茶酚和亚硝酸异戊酯之间的反应产生的重氮盐。所得材料用于固定 Pd 纳米颗粒，从而获得用于丙烯酸甲酯/苯乙烯和芳基碘化物之间的 Heck 反应的活性和可回收催化剂。
