HQ and CC exhibited a reversible quinolinic form with a pair of redox peaks, while the oxidation reaction of RS is irreversible. This is attributed to the charge density, which is different in each isomer due to the position of the two hydroxyl functional groups on the benzene ring [33]....
1,2,4-Trimethylbenzene (mesitylene) is an aromatic hydrocarbon compound commonly present in commercial solvents encompassing their boiling range. Mesitylene are the most common isomer used in commercial applications. Aromatic hydrocarbons in hydrocarbon solvents are predominantly alkylated one ring structures...
nitrogen atmosphere. The mixture was heated to 80° C. overnight and the reaction was traced by TLC. (ethyl acetate: hexane=1:1). Then the reaction mixture was cooled to 10° C. and water was added. A precipitate was formed, which was filtered off, washed with water and dried. 4.8 ...
Thus our work not only raise the first example of π- stacking radical cation with single phenyl ring of weak conductivity, but also lead to a steric control synthesis and provide a systematic study of conductive π-stacking radical cations. Isolation of such radical species together with...
with the nitrogen atom to which they are attached, a saturated carbonaceous 5- or 6-membered ring or a saturated 5- or 6-membered ring which can comprise one or more heteroatoms, wherein said ring is unsubstituted or substituted by a halogen atom, a hydroxyl radical, a (C1-C6)alkyl rad...
Polymer Synthesis All the polymers Va{f were synthesized from di- amine II and dianhydrides IIIa{f, by a conventional two-step procedure ring-opening polyaddition at room temperature to poly(amic acid)s IV, followed by se- quential heating to 250 C or treatment with a mixture of Ac2O/...
