Application

4-Bromophenyl methyl sulfone may be used to synthesize:
  • biaryl methyl sulfones
  • 5-[[-4-(methylsulfonyl)phenyl]thio]thiophene-2-sulfonamide
  • 1-[4-(methylsulfonyl)phenyl]-1H-pyrazole (Hmsppz)
  • DuP 697 via reaction with (5-chloro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)thiophen-2-yl)trimethylsilane

4-Bromophenyl methyl sulfone (1-bromo-4-(methylsulfonyl)benzene) can undergo coupling reaction with benzene sulfonamide in the presence of copper(I)iodide to form the corresponding N-aryl sulfonamide.

A new approach to obtain green-emitting iridium(III) complexes is described. The synthetic approach consists of introducing a methylsulfone electron-withdrawing substituent into a 4-phenylpyrazole cyclometalating ligand in order to stabilize the highest-occupied molecular orbital (HOMO). Six new complexes have been synthesized

A series of 5-(arylthio)-, 5-(arylsulfinyl)-, and 5-(arylsulfonyl)thiophene-2-sulfonamides is described and anticonvulsant activities are listed for the compounds. In most cases, the sulfones had the highest activity and the sulfides the least. Sulfones with 3- or 4-halo substituents generally had the
