Wang, Kaizhi; Jiang, Pengbo; Yang, Ming; Ma, Ping; Qin, Jiaheng; Huang, Xiaokang; Ma, Lei; Li, Rong published the article 《Metal-free nitrogen -doped carbon nanosheets: a catalyst for the direct synthesis of imines under mild conditions》. Keywords: transfer hydrogenation nitrile nitrogen doped carbon nanocatalyst; imine preparation amine oxidation nitrile nitrogen doped carbon nanocatalyst.They researched the compound: Picolinamide( cas:1452-77-3 ).SDS of cas: 1452-77-3. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:1452-77-3) here.
Herein, a highly stable, porous, multifunctional and metal-free catalyst was developed, which exhibited significant catalytic performance in the oxidation of amines and transfer hydrogenation of nitriles under mild conditions; this could be attributed to the presence of numerous active sites and their outstanding BET surface area. The obtained results showed that most of the yields of imines exceeded 90%, and the cycling performance of the catalyst could be at least seven runs without any decay in the reaction activity, which could be comparable to those of metal catalysts. Subsequently, a kinetic study has demonstrated that the apparent activation energy for the direct synthesis of imines from amines is 67.39 kJ mol-1, which has been performed to testify that the catalytic performances are rational. Via catalyst characterizations and exptl. data, graphitic-N has been proven to be the active site of the catalyst. Hence, this study is beneficial to comprehend the mechanism of action of a metal-free N-doped carbon catalyst in the formation of imines.
From this literature《Metal-free nitrogen -doped carbon nanosheets: a catalyst for the direct synthesis of imines under mild conditions》,we know some information about this compound(1452-77-3)SDS of cas: 1452-77-3, but this is not all information, there are many literatures related to this compound(1452-77-3).
