Synthesis of new (4-alkylamino-4'-fluoro)-diphenyl sulphones with potential biological activity

In the present work, we report the synthesis and characterization of five (4-alkylalmino-4'-fluoro)-diphenyl sulphones, four of which have not been described before. In a preliminary evaluation of their biological activity, these products showed no effect on several Gram-positive and Gram-negative bacteria and yeasts.
