A facile and green chemical approach was successfully developed to construct functionalized quinolinones utilizing substituted alcohols, alkyl acetoacetate, α-bromo ketones. Various bearing either electron-rich or electron-deficient groups at different positions were synthesized in moderate good yields under mild reaction conditions. The plausible mechanistic pathway for this transformation is supported by experimental evidence control experiments. This simple synthesizing could open new avenues discovering novel biological pharmaceutical compounds. use of affordable nickel catalysts, conditions, operational simplicity, high atom economy are attractive features method. Furthermore, the synthetic efficiency has been demonstrated through gram-scale Our research also provides valuable insights into photophysical properties derivatives. Notably, compound 6n exhibited highest Stokes shift (216 nm) DCM solvent. compounds 5d 6j showed positive solvatochromism, displaying a stronger emission as solvent polarity increased. Additionally, displayed aggregation-induced (AIE) DMSO : water mixture, making it suitable security ink, highlighting its potential applications various fields.

Abstract A straightforward and practical nucleophile‐induced synthetic route for the synthesis of thermally stable, fluorescently active, functionalized stilbenes has been developed. The described method involves nucleophile‐induced, base‐promoted ring transformation reactions following a more traditional approach. All occur at room temperature, yielding high amounts desired product with minimal byproducts. Due to inclusion donor‐π‐acceptor system, all produced exhibited impressive emission characteristics. resulting band gaps ranged from 3.37 3.93 eV, indicating notable redshift. Solvatochromic investigations underscored these positive impacts. Furthermore, TG‐DTA analysis indicated single‐step evaporation process, compounds stability up 375 °C.
