Abstract

I’
The thesis entitled ”Reaction Kinetics of Some Substituted Pyridines
withAniline Derivatives” comprises three chapters.
Chapter I includes the published literature survey on the nucleophilic
substitutionreactions and their different mechanisms.
Chapter 11includes the experimental part of the thesis. The reaction of
2-chloro-3,5-dinitropyridine 1 with meta and para- substituted anilines 2a-l
_gave the corresponding substitution products 2-anilino-3,5-dinitropyridine
derivatives 3a-1. The structure of the products was determined by the
elementalanalysis, MS, UV, IR and 1HNMR spectra, Eq(3.1).

Eq(3.1)
Chapter III is concerned for the discussion. All products 3a-1 showed
a medium band at range 3270-3300 cm-1 due to N-H streching vibration.
The strong absorptions at 1491-1508 and 1331-1362 cm-1 are assigned to the
assyrnrnetric and symmetric stretching vibrations of the N02 group.
The pronounced red shifts in the electronic spectra of the products
3a-1observed in the main absorption bands are due to the interaction of the
anuno group with the aza groups as well as two nitro groups of the pyridyl
moiety.
The protons chemical shifts of products 3a-1 showed four types of
signals (NH, substituents, aromatic and heteroarometic protons).
