1,2,3,4,5,6,7-hexathiagermepanes: Synthesis, structures, and the ring contraction to 1,2,3,4,5-tetrathiagermolanes
The first 1.2.3.4.5,6.7-hexathiagermepanes Dmp(Ar)GeS6 [Dmp=2.6-dimesitylphenyl, Ar = Mes, Dep (2,6-diethylphenyl), Tip (2,4,6-triisopropylphenyl)] were synthesized along with 1.2.3.4.5-tetrathiagermolanes by sulfurization of the corresponding dihydrogermanes. The hexathiagermepane Dmp(Tip)GeS6 slowly converted to the tetrathiagermolane with release of elemental sulfur owing to the steric hindrance.
