基于二氧化硫自由基歷程構(gòu)建磺酰官能團(tuán)化反應(yīng)的研究
[Abstract]:Sulfur dioxide exists widely in nature. As an important form of S element transformation, sulfur dioxide has been discovered in ancient times when the forefathers of man were active in bonfires. However, sulfur dioxide is also a major component of air pollution. The development of modern industry has led to massive emissions of sulfur dioxide, which can be converted into sulphuric acid, the main component of acid rain, in the air. The trees, buildings and the surface of the earth are corroded greatly. Therefore, sulfur dioxide governance is an important part of environmental governance. The application of sulfur dioxide to organic synthesis is one of the ways. Sulfonyl group is a kind of structure widely existing in all kinds of compounds. It is a common synthetic block and also has biological activity. Therefore, research on the construction of sulfonyl groups has always been a hot topic. Sulfur dioxide inserts one of these very effective methods. Many methods have been developed in the past to react with gaseous sulfur dioxide. Due to the special properties of gaseous sulfur dioxide, it is difficult to control the toxicity and is not suitable for use in the laboratory, so its application in the field of organic synthesis is greatly limited. In recent years, sulfur dioxide carrier reagent has gradually become an effective method for the construction of sulfonyl groups. Compared with previous methods, sulfur dioxide can directly introduce sulfonyl groups without the need to synthesize precursor materials in advance. The synthesis efficiency of sulfonyl groups and the application range of substrates are greatly expanded. In this paper, the solid sulfur dioxide carrier is used as a sulfonyl source to introduce the sulfonyl group into the organic small molecule by the method of free radical series synthesis. The main work is as follows: 1. The synthesis of phenylsulfonyl hydrazide from phenylhydrazine and potassium metasulfite under the condition of non-metallic participation. An oxidative coupling reaction without transition metal was developed. Benzenesulfonyl hydrazide was synthesized by two kinds of hydrazine and potassium pyrosulfite in air. This highly selective reaction, which uses phenylhydrazine as the aryl coupling component and potassium pyrosulfite as the precursor of sulfur dioxide, provides a new safe green synthesis strategy for the construction of phenylsulfonyl hydrazide. Based on the synthesis of unsymmetrical inner lipids containing sulfonyl functional groups by free radical oxidation of DABSO catalyzed by copper, a novel sulfur dioxide carrier, DABSO, was developed by using diazo salts. The method of constructing unsymmetrical internal lipids containing sulfonyl groups by series cyclization of unsaturated olefin carboxylic acid radicals. It is the first time that DABSO is applied to asymmetric catalysis. This method provides a method for directly introducing sulfonyl functional groups into asymmetric lipids.
