In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 3080-99-7, name is 3,4-Dihydro-2H-benzo[b][1,4]thiazine, introducing its new discovery. HPLC of Formula: C8H9NS
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)
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 3080-99-7, and how the biochemistry of the body works.HPLC of Formula: C8H9NS
