    Facile one‐pot assembly of push-pull imines by a selective C-F substitution process in aryl fluorides

    Herein, we report the synthesis of a series of push–pull imines by considering cyclic diamino substituent at the C‐centre and fluoroaryl substituent at the N‐centre. This has been achieved by a selective aromatic nucleophilic substitution of different fluoroarenes by N‐H‐substituted N‐heterocyclic imines (NHIs) at ambient conditions without any additional reagent. Solid‐state molecular structure analysis reveals the elongation of the central C-N bond of the imine functionality, which is consistent with the push–pull nature of these imines. The push-pull nature of these imines is further validated by computational studies.
