Roundabout Mechanism of Ion–Molecule Nucleophilic Substitution Reactions

Roundabout Mechanism of Ion–Molecule Nucleophilic Substitution Reactions

Roundabout (RA) is an important indirect mechanism for gas-phase X<sup>–</sup> + CH<sub>3</sub>Y → XCH<sub>3</sub> + Y<sup>–</sup> S<sub>N</sub>2 reactions at a high collision energy. It refers to the rotation of the CH<sub>3</sub&...
