A hexagonal ring arrangement found in benzene and other aromatic compounds, consisting of six carbon atoms with alternating single and double bonds between them, and with each carbon atom bonded to a hydrogen atom, or to other atoms or groups of atoms in derivatives of benzene. ...
H-D exchange of benzene with the OH groups of aluminas was investigated using FTIR spectroscopy. The reactions benzene- d 6-alumina and benzene-alumina- d are of first order with respect to OH and benzene concentrations ( E A = 112 kJ/mol). They mainly take place on centers—probably ...
This is for a friend: The worksheet says: Name the following comounds: It has a picture, which is a benzene ring with 2 PhD groups off the 1 and 2...
The presence of coordinated ammonia does not affect the ν(OH) bands of free surface TiOH groups, although surface Ti—O stretching modes (1100–1000 cm–1) are perturbed. The ν(OH) bands shift and broaden upon benzene adsorption both on clean and ammonia-covered surfaces. However, the ...
When crystals of N,N′,N″-trialkyl-1,3,5-benzenetricarboxamides with alkyl groups from pentyl to octadecyl are heated, viscous birefringent fluids are pro... Y.,Matsunaga,Y.,... - 《Molecular Crystals & Liquid Crystals》 被引量: 103发表: 1986年 Mass spectra and photoelectron spectroscopy...
The anhydrous scandium carboxylates Sc(OCOR)3 (R = H, CH3) have long been known to have polymeric structures with six-coordinate scandium.40 Scandium formate has a 2-D polymeric structure whilst in the acetate, chains of Sc3+ ions are bridged by acetate groups with essentially octahedral coo...
The study also reveals that the methylene (-CH 2 ) and methine (-CH) groups of adamantane interact with benzene resulting in different geometrical structures. And it is found that the former complex is stronger than the later. The diamondoid structure of adamantane enables it to interact with...
We focused our in situ refining strategy studies initially on the overall transformation of the Csp2–Csp3/Csp2–O bonds by using 1-(4-methoxyphenyl)-1-propanol (1a) as the model compound because of its lignin-mimetic phenylpropanol structure [(CH3O)Ph-Csp3(OH)–] with only one methoxy...
of benzene withcyclohexanein the presence of catalysts such as HBr-AlBr3, HCl-AlCl3and HFSbF5, withisobutaneas the promoter, under varying temperatures and reaction times. Four representative groups of hydrocarbons were found including cycloalkylbenzenes, substitutedindanesortetralins, C1-C6alkyl...
