Study On Fluorocyclization With Alkenyl Azide

?-tungsten carbide azide is a kind of compound with extraordinary structure and excellent reactivity.This kind of compound was discovered and researched more than 100 years ago.In recent decades,research on it has been developing rapidly.Because of its unique structure,the connection of azide groups to naphthalene greatly activates the reactivity of the material.?-nitride azide compounds can participate in a variety of reaction types,including radical reactions,nucleophilic reactions,decomposition reactions,ring Reaction,electrophilic reaction,etc.?-polyamide azide compounds can often synthesize a variety of nitrogen-containing compounds and provide different CCN synths.However,retaining azides in the final product is very rare and very challenging.Here,we designed and synthesized multiple fluoro-1,3-oxahexyl-2-ones through a novel oxidative fluorination cyclization reaction of azide compounds and synthesized them well.The in-situ removal of the leaving group and the re-functionality of the azide group takes into account the widespread presence of azide groups in organic synthesis.It will be necessary to explore new strategies for the synthesis of organic azides from overlapping azides.And the azide groups remaining in the final product provide many conversion opportunities for the preparation of valuable nitrogen-containing cyclic carbonate skeletons.This thesis is mainly divided into two chapters.Chapter 1: Section 1 describes the brief introduction of ?-vinyl azide compounds and the types of chemical reactions involved,and section 2 describes the related development of iodofluoro reagents.Chapter 2: The basis for the research of this topic and its related experimental design and experimental results.
