| titleOfInvention | Method of producing tetra-(4-fluorosulfonylphenyl)porphine |
| abstract | This invention relates to heterocyclic compounds, in particular to the preparation of tetra (4-fluorosulfonyl-fesh) porphin, which may be used as a catalyst. The goal is to increase the yield of the target product and simplify the process. It is prepared from pyrrole and 4-formylbenzenesulfonyl fluoride in a mixture of xylene and 5% monochloroacetic acid at the boiling point of the reaction mixture (PC). Pre-cooled to 40-70 ° C, the PC is treated with 1.5 volumes of acetone with heating by boiling for 0.5-1 hours. Cnov- provides an increase in the yield of the target product up to 28% and simplifies the process. l |
