| titleOfInvention | Method of producing polyfluoroaryl(trimethyl)silanes |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to a method of producing fluorine-containing aromatic silanes. Disclosed is a method of producing polyfluoroaryl(trimethyl)silanes of formula Ar F -Si (CH 3 ) 3 (I), where by reacting polyfluoroaromatic acids with potassium hydroxide solution to form corresponding potassium or dipotassium salts, followed by reacting the separated salts with trimethylchlorosilane in polar aprotic solvents such as DMF, DMAA, N-methylpyrrolidone, sulpholane, at temperature of 70-130°C. The obtained polyfluoroaryl(trimethyl)silanes are separated using existing methods. Output of desired products is 73-86% with respect to the acid. n EFFECT: disclosed method is simple from the technical perspective and enables to obtain various polyfluoroaryl(trimethyl)silanes with high output from readily available off-the-shelf reactants. n 3 cl, 1 tbl, 14 ex |
