R. Suzuki et al., Synthesis and characterization of 2,6-di-tert-butyl-1-thio-1,4-benzoquinone, the first isolable monothio-1,4-benzoquinone, CHEM COMMUN, (15), 2000, pp. 1357-1358
The title compound, a labile but isolable substance owing to appreciable st

esponding 1,4-benzoquinone and is reduced by water.
