Mesoporous silica/graphene (KIT-6/G) with pendent 3-mercaptopropyl groups has been prepared by condensation of surface silanols and (3-mercaptopropyl)trimethoxysilane (MPTMS). Treatment of the mercaptopropylated with Pd(CH3CN)2Cl2 gave a heterogeneous Pd-catalyst (Pd@KIT-6/G-SH). The catalytic activity of the catalyst was investigated in two types of C-H functionalized for the synthesis of 2-cyanoacetanilide and 2-arylpyridine 1-oxide derivatives via C-H activation. Addnl., for the study of the effect of thiol ligand, the Pd@KIT-6/G was prepared from the treatment of Pd(CH3CN)2Cl2 with KIT-6/G. The catalyst has been successfully recovered and reused without loss of activity over seven cycles of reactions. In the experiment, the researchers used many compounds, for example, 3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8Recommanded Product: 3718-65-8).
3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Recommanded Product: 3718-65-8
