Abstract:
A simple protocol for the three-component intermolecular alkylesterification of styrenes with toluenes and peroxyesters using a copper catalyst is described. A variety of ester-containing complex compounds were synthesized with excellent functional group tolerance and step efficiency. Employing the combination of carboxylic acids and di- tert-butyl peroxide (DTBP) oxidant instead of peroxyesters also gave similar results. In this transformation, aromatic acids, aliphatic acids, and amino acids were suitable substrates.

Intermolecular Forces in Solutions
When the strengths of the intermolecular forces of attraction between solute and solvent species in a solution are no different than those present in the separated components, the solution is formed with no accompanying energy change. Such a solution is called an ideal solution. A mixture of ideal gases (or gases such as helium and argon,...

Esters to Carboxylic Acids: Acid-Catalyzed Hydrolysis
During hydrolysis, the ester is first activated towards nucleophilic attack through the protonation of the carboxyl oxygen atom by the acid catalyst. The protonation makes the ester carbonyl carbon more electrophilic. In the next step, water acts as a nucleophile and adds to the...
