Article abstract of DOI:10.1021/ja00370a039

The reaction of bromine trifluoride with sulfurane 1 gives rise to the first reported isolation of geometrical isomers of 12-S-6 sulfur, the trans- and cis-difluorodialkoxydiarylpersulfuranes 2 and 3.The cis isomer is 1.6 +/- 0.1 kcal/mol more favored in
