The germanedithiols Dmp(Ar)Ge(SH)(2) [Dmp=2,6-dimesitylphenyl; Ar = Dep (2,6-diethylphenyl) 1a, Tip (2,4,6-triisopropylphenyl) 1b] were synthesized by the reduction of hexathiagermepanes Dmp(Ar)GeS6 and tetrathiagermolanes Dmp(Ar)GeS4 with NaBH4. The treatment of 1a with 2 equiv of potassium hydride afforded the dipotassium germanedithiolate 2.
