Amani, Amene published the artcileElectrochemical Synthesis Based on the Oxidation of 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone in the Presence of Nucleophiles, Category: piperazines, the publication is Journal of Organic Chemistry (2012), 77(24), 11302-11306, database is CAplus and MEDLINE.
Electrochem. oxidation of piperazinylphenol I (R = R1 = H) with 2-benzoxazolethiol or 2-benzothiazolethiol yielded the bis(benzoxazolethiyl)phenol I (R = R1 = 2-benzoxazolylthio) and bis(benzothiazolethiyl)phenol I (R = R1 = 2-benzothiazolylthio) in 87% and 93% yields, resp. Further electrochem. oxidation of I (R = R1 = 2-benzothiazolylthio) in the presence of p-toluenesulfinic acid (TsH) gave (tosyl)(benzothiazolylthio)quinone II (Ts = 4-MeC6H4SO2); attempted direct electrochem. synthesis of II from I (R = R1 = H), 2-benzothiazolethiol, and TsH, from I (R = R1 = 2-benzothiazolylthio) and TsH in the absence of elec. potential, and from I (R = Ts; R1 = H) and 2-benzothiazolethiol were not successful. Cyclic voltammetric measurements during the reactions of I (R = H, 2-benzothiazolylthio, Ts; R1 = H, 2-benzothiazolylthio) were used to delineate the mechanisms of formation of I (R = R1 = 2-benzothiazolylthio) and II.
