Is the best example for representing aromatic compounds. Scientists struggled a lot to determine the structure of benzene. Because benzene is unreactive towards addition reactions being a highly unsaturated compound. Thus, it shows exceptional stability. The cyclohexatriene structure for benzene was 1st...

Versions Notes Abstract A series of gallium-containing MFI (Ga-MFI) zeolites with varying Ga2O3/Al2O3ratios were synthesized using hydrothermal synthesis and tested as catalyst in catalytic fast pyrolysis (CFP) of beech wood for aromatic production. The results show that the incorporation of Ga ...

(Supplementary Fig.3and Supplementary Fig.4). Again, at 500 μM substrate concentration, we observed no reactivity in DMSO, but the reactions proceed to give near quantitative2aand2ein DMSO/H2O (1:9). To further confirm the importance of H2O, we conducted the nitro-reduction of1cat 500...
Here we report the preparation of a 2D conjugated aromatic polymer synthesized via C–C coupling reactions between tetrabromopolyaromatic monomers. Pre-arranged monomers in the bulk crystal undergo C–C coupling driven by endogenous solid-state polymerization to produce a crystalline polymer, which can ...
