Synthesis of N,N′-Bis(arylsulfanyl)cyclohexa-2,5-diene-1,4-diimines and N,N′-(Cyclohexa-2,5-diene-1,4-diylidene)bis(arenesulfinamides)

Reactions of (chlorosulfanyl)benzenes with benzene-1,4-diamines afforded new N , N ′-bis(arylsul­fanyl)cyclohexa-2,5-diene-1,4-diimines which were oxidized to N , N ′-(cyclohexa-2,5-diene-1,4-diylidene)­bis(arenesulfinamides) with 2 equiv of m -chloroperoxybenzoic acid. When the oxidation was carried out using 4 equiv of m -chloroperoxybenzoic acid, the corresponding bis-sulfonamides were obtained. The synthesized compounds were predicted in silico to exhibit biological activity with a high probability.
