Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? , Product Details of 3080-99-7, The answer is in thermodynamics and kinetics.In a document type is Patent, and a compound is mentioned, 3080-99-7, Name is 3,4-Dihydro-2H-benzo[b][1,4]thiazine, molecular formula is C8H9NS. In a article£¬once mentioned of 3080-99-7
The invention relates to a bromo two fluorine ethyl acetate as a acylation reagent prepared N – aryl formamide (by machine translation)
The invention discloses a bromo two fluorine ethyl acetate as a acylation reagent prepared N – aryl formamide, to N – alkyl amine as the raw material, bromo two fluorine ethyl acetate as a acylating agent, copper as a catalyst, by adding different ligand, alkali and the like, in a solvent in the reaction, for 100 – 120 C lower, stirring for 10 – 14 hours; the end of the reaction, the reaction solution is filtered, the filtrate obtained; to the filtrate to concentrate and the Rotavapor for removing the solvent the residue obtained, through the silica gel column chromatography of the residue, and by the eluant for executing leaching, according to the actual gradient of collecting the effluent; combining contains product effluent, towards the combined effluent concentrate to solvent, finally through drying under vacuum to obtain the target product. Raw materials of the invention is simple and easy, simple preparation process, less pollution, low energy consumption, advantage of high productive rate. (by machine translation)
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 3080-99-7, help many people in the next few years.Product Details of 3080-99-7
