REACTION OF N-ARYLTHIO-1,4-BENZOQUINONE IMINES WITH BENZENESULFINIC ACID

In reaction with sodium benzenesulfinate in acetic acid benzoquinone imines containing a RC6H4S (R = H, 4-OCH3, 4-Cl, 4-NO2, 2-NO2) group at the nitrogen atom form aryl benzenethiosulfonates and the benzenesulfinate of 2-phenylsulfonyl-4-aminophenol.The introduction of two nitro groups into the phenylthio group creates conditions for reaction in the quinonoid fragment, and here the main products are N-(2,4-dinitrophenylthio)-2(3)-phenylsulphonyl-4-aminophenols.
