The reactions of diazomethane with bis(2-fluoro-2-polyfluoroalkylalkenyl) sulfones are accompanied by dehydrofluorination and lead to the formation of new dipyrazolyl sulfones containing polyfluoroalkyl substituents at position 4 of the pyrazole ring. The structure of four new sulfones was confirmed by X-ray diffraction analysis.

Keywords

diazomethane divinyl sulfides fluorinated divinyl sulfones 1-methyl-4-polyfluoroalkylpyrazoles dehydrofluorination 

Notes

Elemental analysis of the synthesized compounds was performed in the analytical laboratory of the Institute of Organic Chemistry of the National Academy of Sciences of Ukraine.
