On November 20, 2014, Nematollahi, Davood; Momeni, Shima; Khazalpour, Sadegh published an article.Formula: C12H16N2O2 The title of the article was Different strategies in electrochemical synthesis of new mono and di-substituted hydroquinone and benzoquinone. And the article contained the following:
Electrochem. syntheses of 2-indolyl-5-arylsulfonyl-p-benzoquinone derivatives were carried out in two successive oxidation steps. The 1st involves the oxidation of hydroquinone, 4-(piperazin-1-yl)-phenol and 1-(4-(4-hydroxyphenyl)-piperazin-1-yl) ethanone in the presence of arylsulfinic acids as nucleophiles. The authors’ voltammetric data indicate that electrochem. generated p-benzoquinone participates in Michael addition reaction with arylsulfinic acids leading to the 2-(arylsulfonyl) benzene-1,4-diols. The 2nd consists of the oxidation of 2-(arylsulfonyl) benzene-1,4-diols in the presence of 1,2-dimethylindole and the formation of 2-indolyl-5-arylsulfonyl-p-benzoquinone derivatives as the final products. A plausible mechanism for the synthesis of 2-indolyl-5-arylsulfonyl-p-benzoquinone derivatives is also presented. The experimental process involved the reaction of 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone(cas: 67914-60-7).Formula: C12H16N2O2
