Abstract


Sulfur-containing organic matter is a very important class of compounds , such as penicillin , cefotaxime sulfur antibiotics occupy an important place in medicine . But it was not until the fifties of the last century , organic sulfur chemistry really become an important branch of organic chemistry . Organic sulfur chemical dyes , pesticides , pharmaceuticals , organic conductive material and a variety of high-tech industries , it is increasingly broad application prospects tireless research in this area has attracted many of the world's scientists . This paper is divided into three parts : The first part describes the the trivalent manganese acetate induced sulfur radical addition reaction of acetylenic ketones selective synthesis of new sulfur indanone derivatives ; sulfur free air in the second part the selective addition reaction of the base and the alkynyl amide , synthesized the novel sulfur spiro derivative ; third part introduces air sulfur radical with the selective addition reaction of the propargyl ester , synthesized containing acrylate derivatives. The products were identified by NMR, MS has been confirmed that part of the structure was confirmed by X single crystal diffraction .
