Recently, chemists have introduced a groundbreaking gas-phase nucleophilic substitution reaction in which the molecule experiences a distinctive reorientation prior to the nucleophile’s attack, thus preserving the original configuration of the molecule. Theoretical chemist Gábor Czakó, who was not part of the research, commented on the intricate nature of such reactions, implying they could be more […]
