Organic reactions in aqueous medium and development of new ditribromide reagent

Abstract

The contents of this thesis have been divided into two chapters summarizing the results based on the experimental works performed during the complete course of the research period. Each chapter constitutes four sections, sections A-D describing introduction, present work, experimental work and spectral data respectively. Organic transformations in aqueous medium are the theme of first chapter in which various synthetically useful reactions such as tetrahydropyranylation of alcohols and synthesis of tertiary amines are described. The second chapter describes the synthesis of newer tribromide reagent and its utilization in various organic transformations such as bromination, synthesis of benzothiazole from thiourea and thioamide, diacylation of aldehydes and synthesis of various xanthene derivatives from enalizable ketones and 9-phenyl xanthene-9-ol.
