Reaction of an Overcrowded Distibene with Elemental Sulfur and Crystallographic Analysis of the Sulfurization Products

The reaction of a kinetically stabilized distibene bearing 2,6-bis[bis(trimethylsilyl)methyl]-4-[tris(trimethylsilyl)methyl]phenyl (denoted as Bbt) groups with elemental sulfur resulted in the formation of three types of sulfurization products containing two antimony atoms. The first structural identification of the 1,2,4,3,5-trithiadistibolane derivative was achieved by X-ray crystallographic analysis.
