WebOxidation of Alkyl Side-Chains. As noted earlier in section 16.1, alkyl side chains are activated towards oxidation at the benzylic position, because free radicals are stabilized at that position through resonance (see section 16.4.). When heated with aqueous potassium permanganate (KMnO 4) under acidic conditions, alkylbenzenes are oxidized to benzoic … WebAug 29, 2013 · Side chains in conjugated polymers have been primarily utilized as solubilizing groups. However, these side chains have roles that are far beyond. We advocate using side chain engineering to tune a polymer’s physical properties, including absorption, emission, energy level, molecular packing, and charge transport. To date, numerous …
In organic chemistry and biochemistry, a side chain is a chemical group that is attached to a core part of the molecule called the "main chain" or backbone. The side chain is a hydrocarbon branching element of a molecule that is attached to a larger hydrocarbon backbone. It is one factor in determining a … See more The placeholder R is often used as a generic placeholder for alkyl (saturated hydrocarbon) group side chains in chemical structure diagrams.
