N-苯基四氢异喹啉的氧化在DDQ中迅速发生。在环境条件下和在硝基甲烷的存在下,以良好至优异的产率分离出相应的β-硝基胺衍生物。异喹啉和N-苯基取代基的电子性质的变化表明,可以接受广泛的取代基,异喹啉芳族环和C1碳之间的电子连通比N-芳基环更强。将β-硝基胺还原为相应的新型手性邻二胺是直接的。用1检验反应1 H NMR光谱表明该反应通过亚胺离子进行,该亚胺离子随后在处理后与硝基甲烷反应。该信息用于缩短所需的反应时间。

A polymer (e.g., a photocatalytic polymer) that contains chromophoric units therein (e.g., covalently coupled therein, in the polymer backbones and/or side chains), is described. In some embodiments, the polymer comprises: (a) a first ligand as a first repeating monomeric unit therein (e.g., as part of the polymer backbones and/or side chains); (b) a transition metal (e.g., Ru, Ir, Fe, Co, etc.) complexed with said first ligand to form a chromophoric unit or transition metal photocatalyst therewith; and (c) optionally but preferably at least one additional ligand (e.g., one or two) complexed with said transition metal to form said chromophoric unit or transition metal photocatalyst; and (d) optionally but preferably a second monomeric unit copolymerized with said first monomeric unit. Compositions containing the same and methods of using the same are also described.
