In more common language, aromatic compounds also are referred to as “benzene and its derivates.” However, this is not completely accurate as there are other compounds considered to be aromatics, such as azulene (C10H8), whose chemical behavior mimics that of benzene, but that are not deriv...
xylene being ortho, meta, or para according to whether methyl groups are separated by one, two, or three carbon atoms, respectively (which are also referred to as 1,2-dimethylbenzene, 1,3-dimethylbenzene, and 1,4-dimethylbenzene, respectively). Polycyclic aromatic hydrocarbons (PAH) are those ...
Additional solvents, which may be used alone or together, or with the aforementioned solvents are amides such as formamide, acetamide, dimethylformamide, diethylformamide, and dimethylacetamide; amines such as diethylenetriamine and triethylenetetramine; alkanolamines such as monoethanolamine, diethanolamine, and...
“Aprotic bases,” as used in the present invention, include bases without an exchangeable proton. Suitable aprotic bases include trialkylamines, such as trimethylamine, triethylamine, diisopropylethylamine and triphenylamine; pyridine; pyrimidine; 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU); and 1,...
Aryl triazenes that are easily prepared from the corresponding anilines are both stable and adaptable to numerous synthetic transformations40–44. Recently, Baran and co-workers used o-tosyl triazene chloride (TzoCl) as the 'port- able desaturase' to install on aliphatic amines or alcohols, and...
Polymersomes, made up of amphiphilic block copolymers, are emerging as a powerful tool in drug delivery and synthetic biology due to their high stability, chemical versatility, and surface modifiability. The full potential of polymersomes, however, has b
A fourth category consists of quaternary ammonium compounds, which are obtained by replacement of all four hydrogen atoms of the ammonium ion, NH4+; an anion is necessarily associated (R4N+X−). Amines are also classified as aliphatic, having only aliphatic groups attached, or aromatic, having...
[31]. Aldehydes are important substrates for some hazard factors such as heterocyclic amines, polycyclic aromatic hydrocarbons, etc. Liu Li found that when aldehydes were added to oil alone, a significant increase in PAHs occurred in the system [32]. Studies also have shown that the addition ...
Various organic as well as inorganic cage-like symmetric molecular systems containing π-network validate this rule. Besides this, it is also noted that there are many cage-like molecular systems where one of the faces is open; we may call such a type of system an open-cage system. ...
In othercases, free—radical adducts are obtained via photogenerated aromatic radicalanions (reactions of aromatic with amines, acids, and arenes) or aromaticradical cations (cyanation). Another possibility is the introduction of asubstituent through a direct attack of photogenerated radicals upon various...
