The aim of the present work is the synthesis of new derivatives of N-substituted diphenyl amine.The Scheme of our work involves Synthesis of different five; six and seven heterocyclic rings starting from diphenyl amine.
First part:
Spectrochemical methodswas employed for determination of wear metals (Fe, Cu, Pb and Al) that result from the internal friction between engine's component after using for a different distances in commercial fuchs lubricating oil. The samples were collected from the engine after running for 0 till 3000Km.
The scheme of this work involves synthesis of different five memberd hetrocyclic rings from ρ-chlorobenzoic hydrazide which was synthesized from it's carboxylic acid.
This work is divided into three parts:
