(ESP) map and spectroscopic analysis of some selected amidoalkyl naphthols. The thermochemical parameters of reactions including enthalpy, internal energy, entropy and Gibbs free energy were also investigated. The theoretically calculated infrared (IR) and 1 H nuclear magnetic resonance (NMR) spectra of title compounds were compared to the experimental data. Based on the results, the synthesis of amidoalkyl

(((4-(1-iminoethyl)phenyl)imino)methyl)phenols were successfully synthesized, characterized, and applied in the one-pot three-component reaction of substituted benzaldehydes, 2-naphthol, and amides for synthesis of 1-amidoalkyl-2-naphthols. These three-component processes occurred under solvent-free reaction conditions at 80 °C. The magnetically recoverable supported Schiffbase metal catalysts can
Zirconocene dichloride (Cp2ZrCl2) was found to be highly efficient catalyst for the synthesis of structurally diverse 1-amidoalkyl-2-naphthols by one-pot multi-component reaction (MCR) of 2-naphthol with a variety of aryl aldehydes and amides under ambient temperature. The activation of both carbonyl groups of aryl aldehydes and the o-quinine methide intermediate accounts for the high reactivity of Cp2ZrCl2.
Silica gel-supported polyphosphoric acid (PPA-SiO2) was found to be an efficient catalyst for the multicomponent condensation reaction of aryl aldehydes, 2-naphthol, and urea or amides to afford the corresponding 1-amidoalkyl-2-naphthols in good to excellent yields. This new approach consistently had short reaction times, high conversions, clean reaction profiles, and simple experimental and workup procedures.

The use of ionic liquid in catalysis is attracting more and more attention in the field of chemistry. In line with the research we have studied Supported Ionic Liquid Catalyst (SILC) which consist of benzimidazolium based ionic liquid immobilized on silica based solid support. The SILC proved to be an efficient heterogeneous catalyst for solvent less synthesis of 1-amidoalkyl naphthols from 2-naphthol, amides and aldehydes. The process represents a simple, ecologically safer, cost effective route to 1-amidoalkyl naphthol with high product quality, as well as easy product recovery and catalyst recycling.
