The invention relates to compounds derived from 2-phenyl-fluorosulfonamides of formula (I) wherein R1, R2, R3 and R4 are as defined in the description and claims, and to a method for producing said compounds by preparing a solution with a copper catalyst selected from copper salts of the group consisting of: Cu(MeCN)PF6, CuOAc, CuBr2, CuCl, CuI, Cu(BF4)H2O or Cu(OSO2CF3)2, a phenanthroiline including neocuproine, bipyridine or phenanthroline as a copper chelating agent and an organic solvent selected from the group consisting of: MeCN, EtOAC, 1,4-dioxane, 1,2-dimethoxyethane, MeNO2, Ph-Cl or 1,2- dichloroethane, followed by adding Et3N•3HF to the resulting suspension, and then adding substituted or non-substituted styrene and Mo(CO)6, where the resulting mixture is heated at 70°C until a gas is produced. Silica gel is subsequently added to the mixture, and the solvent is then left to evaporate under reduced pressure, the fluorosulfonamide being separated in a chromatographic column. |
