dc.description.abstract | PART A CHAPTER-A . I Page No.16 - 17 INTRODUCTION TO HIGH NITROGEN COMPOUNDS, THEIR SYNTHESIS, PROPERTIES AND APPLICATION. CHAPTER-A . II Page No.18 - 50 SOLID PHASE SYNTHESIS OF CYCLIC-ACYCLIC TRIAZENES Several cyclic-acyclic triazenes derived from 4,5-diphenylimidazole and 1,4-di-hydropyridines were synthesized on ion-exchange resin support by the solid phase diazocoupling reaction and the corresponding anions of the substrates. CHAPTER-A . III Page No.51 - 64 quotARYLAZO GROUP TRANSFERquot REACTION OF CYCLIC-ACYCLIC TRIAZENES The cyclic-acyclic triazenes derived from the 1,4-dihydropyridines were used as a substrate for the transfer of the arylazo group to a n-excessive heterocycle, namely indole. PART B CHAPTER-B . I Page No.65 - 99 INTRODUCTION TO PHASE TRANSFER CATALYSTS, THEIR NATURE AND USE IN ORGANIC SYNTHESIS CHAPTER-B . II Page No.100 - 114 OXIDATION OF ALCOHOLS AND SOME BENZYL HALIDES TO THE CORRESPONDING CARBONYL COMPOUNDS USING QUATERNARY AMMONIUMBROMATES Tetra-n-propyl and tetra-n-butylammoniumbromates were used as a primary oxidant in the oxidation of alcohols to the parent carbonyl compounds. CHAPTER-B . III Page No.115 - 131 OXIDATION OF AROMATIC AMINES TO THE NITRO COMPOUNDS USING TETRA-n-ALKYLAMMONIUMBROMATES Tetra-n-propyl and tetra-n-butylammoniumbromates were used for the oxidation of a variety aromatic amines to nitro compounds. Reaction condition and recovery process are simple and yield of products are high. CHAPTER-B . IV Page No.132 - 166 DEOXIMATION USING TETRA-n-ALKYLAMMONIUMBROMATES Tetra-n-propylammoniumbromate was used for the oxidative deoximation of oximes to carbonyl compounds. Reaction conditions were simple and products obtained in high yields. CHAPTER-B . V Page No.167 - 199 OXIDATIVE CLEAVAGE OF gtC=N- OF PHENYLHYDRAZONES AND SEMICARBAZONES Quaternaryammoniumbromates were used as an efficient oxidizing reagent for the oxidative regeneration of carbonyl compounds from their corresponding hydrazones, phenylhydrazones, 2,4-dinitrophenylhydrazones and semicarbazones.
