Adilina, Indri Badria; Widjaya, Robert Ronal; Hidayati, Luthfiana Nurul; Supriadi, Edi; Safaat, Muhammad; Oemry, Ferensa; Restiawaty, Elvi; Bindar, Yazid; Parker, Stewart F. published an article in 2021, the title of the article was Understanding the Surface Characteristics of Biochar and Its Catalytic Activity for the Hydrodeoxygenation of Guaiacol.Formula: C8H10O2 And the article contains the following content:

Biochar (BCR) was obtained from the pyrolysis of a palm-oil-empty fruit bunch at 773 K for 2 h and used as a catalyst for the hydrodeoxygenation (HDO) of guaiacol (GUA) as a bio-oil model compound Brunauer-Emmet-Teller surface area anal., NH3 and CO2-temperature-programmed desorption, scanning electron microscope-dispersive X-ray spectroscopy, CHN anal. and X-ray fluorescence spectroscopy suggested that macroporous and mesoporous structures were formed in BCR with a co-presence of hydrophilic and hydrophobic sites and acid-base behavior. A combination of IR, Raman and inelastic neutron scattering (INS) was carried out to achieve a complete vibrational assignment of BCR. The CH-OH ratio in BCR is ∼5, showing that the hydroxyl functional groups are a minority species. There was no evidence for any aromatic C-H stretch modes in the IR, but they are clearly seen in the INS and are the majority species, with a ratio of sp3-CH:sp2-CH of 1:1.3. The hydrogen bound to sp2-C is largely present as isolated C-H bonds, rather than adjacent C-H bonds. The Raman spectrum shows the characteristic G band (ideal graphitic lattice) and three D bands (disordered graphitic lattice, amorphous carbon, and defective graphitic lattice) of sp2 carbons. Adsorbed water in BCR is present as disordered layers on the surface rather than trapped in voids in the material and could be removed easily by drying prior to catalysis. Catalytic testing demonstrated that BCR was able to catalyze the HDO of GUA, yielding phenol and cresols as the major products. Phenol was produced both from the direct demethoxylation of GUA, as well as through the demethylation pathway via the formation of catechol as the intermediate followed by deoxygenation. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Formula: C8H10O2

On April 21, 2022, Ito, Mamoru; Onoda, Hideaki; Takaki, Asahi; Shibata, Takanori published an article.COA of Formula: C15H13NO The title of the article was Gold-Catalyzed Cascade and Divergent Synthesis of Indolobenzazepines and Indoloquinolines from Nitrogen-Tethered 1,8-Diynes. And the article contained the following:

Authors describe the divergent construction of two nitrogen-containing polycyclic systems by gold-catalyzed cycloisomerizations. The gold-catalyzed cascade hydroamination and 7-endo-dig-selective cycloisomerization of nitrogen-tethered 1,8-diynes yielded indolo[1,7-ab]benzazepines in one pot. In contrast, when Johnphos-coordinated gold catalyst was used, the same 1,8-diynes were transformed into indolo[1,2-a]quinolines by 6-endo-dig-selective cycloisomerization along with rearrangement of the substituent on one of the alkynes. The reaction of a naphthalene-tethered substrate provided a helically chiral aza[6]helicene. The experimental process involved the reaction of 2-((4-Methoxyphenyl)ethynyl)aniline(cas: 157869-15-3).COA of Formula: C15H13NO
