Synthesis and structure of the first germaketenedithioacetal

Abstract

Treatment of an overcrowded diarylgermylene Tbt(Tip)Ge: 1{Tbt = 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl, Tip = 2,4,6-triisopropylphenyl} with carbon disulfide affords the first germaketenedithioacetal derivative 3 as a stable orange crystalline compound, for which the molecular structure is established by X-ray crystallographic analysis.
