So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Zhang, Jingyu; Chen, Shiya; Chen, Fangfang; Xu, Wensheng; Deng, Guo-Jun; Gong, Hang researched the compound: 5-Fluoroindoline( cas:2343-22-8 ).HPLC of Formula: 2343-22-8.They published the article 《Dehydrogenation of Nitrogen Heterocycles Using Graphene Oxide as a Versatile Metal-Free Catalyst under Air》 about this compound( cas:2343-22-8 ) in Advanced Synthesis & Catalysis. Keywords: graphene oxide nitrogen heterocycle dehydrogenation catalyst green chem. We’ll tell you more about this compound (cas:2343-22-8).
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 mols. with different conjugated systems indicated that both the oxygen-containing groups and large π-conjugated system in GO sheets are essential for this reaction.
Compound(2343-22-8)HPLC of Formula: 2343-22-8 received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(5-Fluoroindoline), if you are interested, you can check out my other related articles.
