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)
摘要:
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-chloroperoxybenzoicacid. When the oxidation was carried out using 4 equiv of m-chloroperoxybenzoicacid, the corresponding bis-sulfonamides were obtained. The synthesized

The three component reaction of the zwitterion generated from dimethylacetylenedicarboxylate and isocyanides with various quinoneimides is described. The reaction afforded the corresponding γ-spiroiminolactams in good yields.
