Concerted Nucleophilic Aromatic Substitution Reactions [PDF]

open access: yesAngewandte Chemie - International Edition, 2019
AbstractRecent developments in experimental and computational chemistry have identified a rapidly growing class of nucleophilic aromatic substitutions that proceed by concerted (cSNAr) rather than classical, two‐step, SNAr mechanisms. Whereas traditional SNAr reactions require substantial activation of the aromatic ring by electron‐withdrawing ...

Dehalogenation of Aromatics by Nucleophilic Aromatic Substitution

open access: yesEnvironmental Science & Technology, 2014
Nucleophilic aromatic substitution has been implicated as a mechanism for both the biotic and abiotic hydrodehalogenation of aromatics. Two mechanisms for the aqueous dehalogenation of aromatics involving nucleophilic aromatic substitution with hydride as a nucleophile are investigated using a validated density functional and continuum solvation ...

On the Frontier Between Nucleophilic Aromatic Substitution and Catalysis [PDF]

open access: yesChemistry - A European Journal, 2014
AbstractA study on the arylation of heteroatom nucleophiles by using activated haloarenes, with or without metal catalysts, is reported. A discussion concerning the involvement of traces of metals is presented, supported by an unexpected ''ligand'' effect in the absence of added metal catalysts.

Nucleophilic aromatic substitution on aromatic aldimines

Tetrahedron Letters, 1993
Abstract Ortho-methoxy-substituted benzaldimines derived from 3-amino-2,4-dimethylpentane undergo efficient nucleophilic aromatic substitution with typical organolithium reagents. The aldimine products can be hydrolyzed under mild conditions to provide ortho-alkyl or ortho-phenyl benzaldehyde derivatives.
