“…In reference [31], the authors considered the impact of halogen atoms (Cl, Br, and I) on the interconversion of kinetically (a) and thermodynamically (b) controlled regioisomers, leading to equilibrium mixtures of the isomers. The study reveals that thermodynamic favorability for the formation of thermodynamically controlled regioisomers increases in the order Cl < Br ≈ I and correlates well with the energy difference between S•••N and S•••X (where X = Cl, Br, or I) chalcogen bonds in kinetically and thermodynamically controlled products.…”
