Vicarious nucleophilic substitution
From Wikipedia, the free encyclopedia
Vicarious nucleophilic substitution in organic chemistry is a special type of nucleophilic aromatic substitution in which a nucleophile replaces hydrogen and not an aromatic substituent like a halogen that is ordinarily encountered in this reaction type. This reaction type was introduce in 1987 by Mieczyslaw Makosza and Jerzy Winiarski.[1][2]
It is typically encountered with nitroarenes and especially with carbon nucleophiles, resulting in new alkylated arenes. Carbon nucleophiles carry a electron-withdrawing group and a nucleofuge:
