The observed 2-methyl 1,4 benzoquinone and traces of phenol and benzene were determined to be secondary products.Nektarios Moschonas and Demetrios Danalatos and Sotirios GlavasAtmospheric EnvironmentMoschonas, N., Danalatos, D., Glavas, S., 1998. The effect of O2 and NO2 on the ring ...
It was observed that a polar substituent in the benzene ring mainly affected ka in the nitric acid oxidation of diphenylmethanes. The mechanism of reaction of these benzyl compounds is discussed.doi:10.1016/S0040-4020(01)93076-5Y. Ogata
[30] measured PM2.5, NO2 and benzene in and outside 24 schools located within 400 m of motorways, and Roorda Knape et al. [1, 31] measured PM10, PM2.5, benzene, NO2 and black smoke in six residential areas with homes located within 300 m from a major motorway. Kramer et al. [...

Source of materialThe title compound was synthetized with a 86% yield byrefluxing for 20 h in benzene 4-(4-chlorophenyl)-4-hydroxy-piperidine and [2-(bromomethyl)cyclopentyl]-(4-fluoro-phenyl)-methanone [1] in 2:1 molar ratio and was thenrecrystallized from methanol (mp 377 K – 379 K...
The separation of the diene adducts from each other and from the aromatic compounds was greatly improved using benzene as eluent at 5- 10°C. The diene adducts were readily separated on the Waters liquid chromatograph. Reactions of dienes 1am, 12m, and 12n with acids Boron trifluoride-etherate...
(HEDMs),extensive theoretical calculations were carried out to investigate on a series of polynitrotriprismanes (PNNPs): C6H6-n(NO2)n (n= 1-6).Heats of formation (HOFs), strain energies (SE), and disproportionation energy (DE) were obtained using B3LYP/6-311+G(2df,2p)//B3LYP/6-31...
Therefore, the electronegativity of the heteroatom in the arene ring highly influences the interactions within the substituted system. Depending on the type of substituent— electron-withdrawing (NO2) or electron-donating (NH2)—interactions can be enhanced or weakened with respect to benzene ...
On the other hand, the LUMO orbital showed significant differences between the compound Azo1 and its nitro congeners (Azo2 to Azo4). In Azo1, the LUMO orbital is related to a pi delocalization system that encompasses the phenyl azo ring, the phenol ring, and the imine group, while in ...
