Song, Lijuan published the artcileNatural gallic acid catalyzed aerobic oxidative coupling with the assistance of MnCO3 for synthesis of disulfanes in water, SDS of cas: 119-80-2, the publication is Green Chemistry (2019), 21(6), 1432-1438, database is CAplus.
To pursue a sustainable approach for such a synthesis, an aerobic oxidative coupling method for the efficient preparation of organic disulfanes RSSR1 [R = 4-MeC6H4, cyclohexyl, 2-thienyl, etc.; R1 = t-Bu, 4-ClC6H4, 4-H2NC6H4, etc.], using a low-toxic natural gallic acid as an organocatalyst, inexpensive MnCO3 as a cocatalyst, O2 as the terminal oxidant and water as the solvent, was successfully developed. Such metal-organic cooperative catalytic protocol provided an access to various sym. and unsym. disulfanes in up to 99% yield. Gram scale synthesis with practical convenience and low loading of catalysts further illustrated the practicability of our method.
