Synthesis and Structural Analysis of Schiff Bases Derived from Aromatic Aldehydes 

CHAPTER ONE

1.1 Background to the Study

Schiff bases are important organic compounds formed by the condensation of primary amines with aldehydes or ketones. They contain an imine functional group (C=N), which plays a vital role in their chemical reactivity and coordination behavior. These compounds have attracted attention because of their wide applications in catalysis, medicine, and analytical chemistry (Iqbal et al., 2020).
In recent years, researchers have focused on Schiff bases derived from aromatic aldehydes because they often exhibit enhanced stability, unique electronic properties, and biological activity. Moreover, structural analysis using techniques such as infrared and ultraviolet spectroscopy provides valuable insights into their bonding and geometry (Raman et al., 2017). Understanding these features helps scientists design better catalysts and drug candidates.

1.2 Statement of the Problem

Although Schiff bases are well-studied compounds, new derivatives continue to emerge, especially those synthesized from locally available aromatic compounds. However, limited structural data exist on these newly derived compounds, and this gap restricts their potential applications in industrial and pharmaceutical chemistry.

1.3 Objectives of the Study

1. To synthesize Schiff bases using selected aromatic aldehydes and primary amines.

2. To characterize the synthesized compounds using spectroscopic methods.

3. To analyze their structural properties and bonding characteristics.

1.4 Significance of the Study

This study will enhance understanding of Schiff base chemistry and its applications in coordination and medicinal chemistry. Furthermore, the findings will provide structural information that supports future research on metal–ligand interactions and catalysis. It also aligns with global efforts to develop multifunctional compounds for industrial and pharmaceutical use.

1.5 Scope of the Study

The research will focus on the synthesis and structural analysis of aromatic Schiff bases under laboratory conditions. Only infrared and UV–Vis spectroscopic techniques will be employed for characterization.
