| Summary: | Заглавие с экрана Arenediazonium salts ArN2+–OTs are one of the most important building blocks in the classical organic synthesis and promising reagents. One of up-to-date trend of diazonium salt’s chemistry is c-c coupling. Reactions like this usually carry out in the presence of palladium catalysts. Meanwhile the main shortage of this method is high cost of catalysts. Compound Fe(acac)3, which usually use for cross-coupling reaction, can become potential alternative. In this paper we talk about reaction of thermal analysis of nitro arenediazoniumtosylate (NADT) depending on the solvent (DMSO, DMF, THF), the molar percentage of catalyst tris(acetylacetonato)iron (III), temperature and their combination. We carried out some reactions and obtained products of interaction of NADT with solvents, catalyst and styrene. It means that this research gives a clue to control of reactivity of arenediazonium salts depending of condition of reaction. |
