Graphene oxide (GO) has been developed as an inexpensive, environmental friendly, metal‐free carbocatalyst for the dehydrogenation of nitrogen heterocycles. Valuable compounds, such as quinoline, 3,4‐dihydroisoquinoline, quinazoline, and indole derivatives, have been successfully used as substrates. The investigation of various oxygen‐containing molecules with different conjugated systems indicated
氧化石墨烯(GO)已开发为一种廉价,环保,无金属的碳催化剂,可用于氮杂环的脱氢。有价值的化合物,例如喹啉,3,4-二氢异喹啉,喹唑啉和吲哚衍生物已成功用作底物。对具有不同共轭体系的各种含氧分子的研究表明,GO片中的含氧基团和较大的π共轭体系对于该反应都是必不可少的。
