WebNov 20, 2024 · To build on Tyberius' point: reactivity (reaction rate, determined by activation energy) is determined not only by the energy of the starting material, but also the energy of the transition state (or intermediate, by the Hammond postulate). Obviously, this depends on the exact reaction pathway under consideration. WebJan 18, 2024 · Electrophilic aromatic substitution (EAS) is one of the most fundamental reactions in organic chemistry. Using an oriented external electric field (OEEF) instead of traditional reagents to tune the EAS reactivity can offer an environmentally friendly method to synthesize aromatic compounds and hold the promise of broadening its scope.
