The catalyst-free green synthesis and QTAIM analysis of anilino-1,4-naphthoquinones as molecular wires.

ABSTRACT: Molecular wires represent a cornerstone of next-generation nanoelectronics, yet the design of highly efficient, short molecular conductors remains a significant challenge. In this study, we present a catalyst-free, green synthetic route for the preparation of anilino-1,4-naphthoquinone enaminone derivatives via aqueous-phase Michael addition between anilines and 1,2-naphthoquinone-4-sulfonic acid sodium salt. The reaction proceeds rapidly at room temperature, yielding products with excellent efficiency (96-98%) and exceptional purity, as confirmed by comprehensive spectroscopic characterization (FT-IR, UV-Vis, ¹H and ¹³C NMR, MS) and elemental analysis. Single-crystal X-ray diffraction further validated the molecular structures of representative compounds. Theoretical
