Bis(N-methyl-N-phenylcarbamoyl)disulfane

Abstract

The title compound, C16H16N2O2S2, has been synthesized by several different high-yield routes, and has been encountered as a co-product in a number of reaction pathways, ever since it became of interest to our research program over 30 years ago. We now confirm the proposed molecular structure in which the molecule exhibits a twofold axis of symmetry through the mid-point of the S—S bond and the two planes defined by the (carbamoyl)sulfenyl moieties are essentially perpendicular to each other [dihedral angle = 81.55 (14)°].
