Vicarious nucleophilic substitution

Jump to navigation Jump to search

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:
