Introduction 1. Introduction The initial aryl migration reaction was published by Wieland in 1911 [1]. Due to the fact then, The very first aryl migration reaction was published by Wieland in 1911 [1]. Considering that then, a lot of a lot of research have the literature, presenting synthetically useful transformations [2,3]. The studies have graced graced the literature, presenting synthetically valuable transformations [2,3]. The Smiles rearrangement, discovered in 1930 intramolecular S Ar reaction taking Smiles rearrangement, discovered in 1930 [4,5], an [4,5], an intramolecular SNAr reaction N taking location in the ipso position of a substituted aromatic program, example of an aryl miplace in the ipso position of a substituted aromatic system, is an is definitely an example of an aryl migration below standard circumstances (Scheme [6,7]. This SS Ar reaction, like the vicarious gration beneath standard circumstances (Scheme 1) 1) [6,7]. This NNArreaction, just like the vicarious nucleophilic substitution, investigated by the team MMkosza [8], often characteristics activanucleophilic substitution, investigated by the team ofof akosza [8], often characteristics activation tion utilizing electron-withdrawing groups, normally a nitro group [6,7,92]. Nevertheless,initial applying electron-withdrawing groups, typically a nitro group [6,7,92]. Even so, the the very first identification of this rearrangement by Smiles was on naphthalene derivatives which identification of this rearrangement by Smiles was on naphthalene derivatives which lacked lacked activating [5]. activating groups groups [5].Copyright: 2021 by the authors.
