However, the nucleophilic aromatic substitution (S N Ar) reactions that are common in drug development can proceed by a variety of mechanisms and depend on solvent effects, which methods like DFT can ...

In undergraduate organic chemistry courses, nucleophilic substitution reactions are often carried out as an experiment. Reactions that occur at saturated carbons are chiefly categorized as S N 1 or S ...

The classic nucleophilic aromatic substitution (S N Ar) mechanism – described in all undergraduate textbooks as a two-step process – doesn’t apply to most molecules, US researchers have revealed.. The ...
