Utilizing radical chemistry, a new general C-C bond formation on the furoxan ring was developed. By taking advantage of the lability of furoxans, a wide variety of transformation of the synthesized furoxans have been demonstrated. Thus, this developed methodology enabled not only the modular synthesis of furoxans but also short-step transformations of carboxylic acids to a broad range of functional groups.

The Michael acceptor 1,4-bis-(E)-2-(arylsulfonylvinyl)benzene was exploited to prepare a new series of bis heterocycles-(1,4-phenylene)bis(arylsulfonylpyrrole) and (1,4-phenylene)bis(arylsulfonyl pyrazole). All of the compounds were tested for antioxidant activity. Amongst the tested compounds, 1,4-bis-(E)-2-(arylsulfonylvinyl)benzene (5) was found to be the best potential antioxidant agent.

The mass spectral studies of arylsulphonylacetic acids reveal that the skeletal rearrangement via aryl-oxygen bond formation is predominant with a weak competing alkyl migration.A linear correlation is obtained between the intensities of + ions, i.e. +> and the Hammett substituent constants.
